nghttp2 1.52.0-1+deb12u1 (deb) pkg:deb/debian/[email protected]%2Bdeb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1.52.0-1+deb12u1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 14th percentile Description nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK stream. nghttp2 v1.61.0 mitigates this vulnerability by limiting the number of CONTINUATION frames it accepts per stream. There is no workaround for this vulnerability.

openldap 2.5.13+dfsg-5 (deb) pkg:deb/debian/[email protected]%2Bdfsg-5?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.5.13+dfsg-5 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 54th percentile Description libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux. Affected range >=2.5.13+dfsg-5 Fixed version Not Fixed EPSS Score 0.41% EPSS Percentile 74th percentile Description contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation. Affected range >=2.5.13+dfsg-5 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 10th percentile Description slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill cat /pathname" command, as demonstrated by openldap-initscript. Affected range >=2.5.13+dfsg-5 Fixed version Not Fixed EPSS Score 0.42% EPSS Percentile 75th percentile Description The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.

systemd 252.26-1~deb12u2 (deb) pkg:deb/debian/[email protected]~deb12u2?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=252.26-1~deb12u2 Fixed version Not Fixed EPSS Score 0.10% EPSS Percentile 41st percentile Description An issue was discovered in systemd 253. An attacker can modify the contents of past events in a sealed log file and then adjust the file such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." Affected range >=252.26-1~deb12u2 Fixed version Not Fixed EPSS Score 0.10% EPSS Percentile 41st percentile Description An issue was discovered in systemd 253. An attacker can truncate a sealed log file and then resume log sealing such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." Affected range >=252.26-1~deb12u2 Fixed version Not Fixed EPSS Score 0.09% EPSS Percentile 39th percentile Description An issue was discovered in systemd 253. An attacker can modify a sealed log file such that, in some views, not all existing and sealed log messages are displayed. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." Affected range >=252.26-1~deb12u2 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description systemd, when updating file permissions, allows local users to change the permissions and SELinux security contexts for arbitrary files via a symlink attack on unspecified files.

m4 1.4.19-3 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1.4.19-3 Fixed version Not Fixed EPSS Score 2.87% EPSS Percentile 91st percentile Description Unspecified vulnerability in GNU m4 before 1.4.11 might allow context-dependent attackers to execute arbitrary code, related to improper handling of filenames specified with the -F option. NOTE: it is not clear when this issue crosses privilege boundaries. Affected range >=1.4.19-3 Fixed version Not Fixed EPSS Score 1.89% EPSS Percentile 89th percentile Description The (1) maketemp and (2) mkstemp builtin functions in GNU m4 before 1.4.11 do not quote their output when a file is created, which might allow context-dependent attackers to trigger a macro expansion, leading to unspecified use of an incorrect filename.

perl 5.36.0-7+deb12u1 (deb) pkg:deb/debian/[email protected]%2Bdeb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=5.36.0-7+deb12u1 Fixed version Not Fixed EPSS Score 0.33% EPSS Percentile 71st percentile Description HTTP::Tiny before 0.083, a Perl core module since 5.13.9 and available standalone on CPAN, has an insecure default TLS configuration where users must opt in to verify certificates. Affected range >=5.36.0-7+deb12u1 Fixed version Not Fixed EPSS Score 0.24% EPSS Percentile 65th percentile Description _is_safe in the File::Temp module for Perl does not properly handle symlinks.

shadow 1:4.13+dfsg1-1 (deb) pkg:deb/debian/shadow@1:4.13%2Bdfsg1-1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1:4.13+dfsg1-1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description shadow 4.8, in certain circumstances affecting at least Gentoo, Arch Linux, and Void Linux, allows local users to obtain root access because setuid programs are misconfigured. Specifically, this affects shadow 4.8 when compiled using --with-libpam but without explicitly passing --disable-account-tools-setuid, and without a PAM configuration suitable for use with setuid account management tools. This combination leads to account management tools (groupadd, groupdel, groupmod, useradd, userdel, usermod) that can easily be used by unprivileged local users to escalate privileges to root in multiple ways. This issue became much more relevant in approximately December 2019 when an unrelated bug was fixed (i.e., the chmod calls to suidusbins were fixed in the upstream Makefile which is now included in the release version 4.8). Affected range >=1:4.13+dfsg1-1 Fixed version Not Fixed EPSS Score 0.15% EPSS Percentile 51st percentile Description initscripts in rPath Linux 1 sets insecure permissions for the /var/log/btmp file, which allows local users to obtain sensitive information regarding authentication attempts. NOTE: because sshd detects the insecure permissions and does not log certain events, this also prevents sshd from logging failed authentication attempts by remote attackers.

sqlite3 3.40.1-2 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=3.40.1-2 Fixed version Not Fixed EPSS Score 0.22% EPSS Percentile 61st percentile Description A Memory Leak vulnerability exists in SQLite Project SQLite3 3.35.1 and 3.37.0 via maliciously crafted SQL Queries (made via editing the Database File), it is possible to query a record, and leak subsequent bytes of memory that extend beyond the record, which could let a malicious user obtain sensitive information. NOTE: The developer disputes this as a vulnerability stating that If you give SQLite a corrupted database file and submit a query against the database, it might read parts of the database that you did not intend or expect.

util-linux 2.38.1-5+deb12u1 (deb) pkg:deb/debian/[email protected]%2Bdeb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.38.1-5+deb12u1 Fixed version Not Fixed EPSS Score 0.05% EPSS Percentile 18th percentile Description A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4.

apt 2.6.1 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.6.1 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 54th percentile Description It was found that apt-key in apt, all versions, do not correctly validate gpg keys with the master keyring, leading to a potential man-in-the-middle attack.

net-tools 2.10-0.1 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.10-0.1 Fixed version Not Fixed EPSS Score 0.06% EPSS Percentile 26th percentile Description ifconfig, when used on the Linux kernel 2.2 and later, does not report when the network interface is in promiscuous mode if it was put in promiscuous mode using PACKET_MR_PROMISC, which could allow attackers to sniff the network without detection, as demonstrated using libpcap.

krb5 1.20.1-2+deb12u2 (deb) pkg:deb/debian/[email protected]%2Bdeb12u2?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1.20.1-2+deb12u1 Fixed version Not Fixed EPSS Score 0.10% EPSS Percentile 41st percentile Description An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data.

openssl 3.0.13-1~deb12u1 (deb) pkg:deb/debian/[email protected]~deb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=3.0.11-1~deb12u2 Fixed version Not Fixed EPSS Score 0.07% EPSS Percentile 30th percentile Description OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack."

glib2.0 2.74.6-2+deb12u3 (deb) pkg:deb/debian/[email protected]%2Bdeb12u3?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.74.6-2+deb12u3 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 53rd percentile Description GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.

gcc-12 12.2.0-14 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=12.2.0-14 Fixed version Not Fixed EPSS Score 0.07% EPSS Percentile 32nd percentile Description libiberty/rust-demangle.c in GNU GCC 11.2 allows stack consumption in demangle_const, as demonstrated by nm-new.

gnupg2 2.2.40-1.1 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.2.40-1.1 Fixed version Not Fixed EPSS Score 0.05% EPSS Percentile 18th percentile Description GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached, compressed down to just a few KB.

coreutils 9.1-1 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=9.1-1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition.

libxml2 2.9.14+dfsg-1.3~deb12u1 (deb) pkg:deb/debian/[email protected]%2Bdfsg-1.3~deb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=2.9.14+dfsg-1.3~deb12u1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 11th percentile Description An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c.

curl 7.88.1-10+deb12u6 (deb) pkg:deb/debian/[email protected]%2Bdeb12u6?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=7.88.1-10+deb12u6 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 14th percentile Description libcurl skips the certificate verification for a QUIC connection under certain conditions, when built to use wolfSSL. If told to use an unknown/bad cipher or curve, the error path accidentally skips the verification and returns OK, thus ignoring any certificate problems.

tar 1.34+dfsg-1.2+deb12u1 (deb) pkg:deb/debian/[email protected]%2Bdfsg-1.2%2Bdeb12u1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1.34+dfsg-1.2+deb12u1 Fixed version Not Fixed EPSS Score 0.69% EPSS Percentile 81st percentile Description Tar 1.15.1 does not properly warn the user when extracting setuid or setgid files, which may allow local users or remote attackers to gain privileges.

gnutls28 3.7.9-2+deb12u3 (deb) pkg:deb/debian/[email protected]%2Bdeb12u3?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=3.7.9-2+deb12u3 Fixed version Not Fixed EPSS Score 0.85% EPSS Percentile 83rd percentile Description The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.

libgcrypt20 1.10.1-3 (deb) pkg:deb/debian/[email protected]?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=1.10.1-3 Fixed version Not Fixed EPSS Score 0.19% EPSS Percentile 57th percentile Description cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for Libgcrypt's ElGamal implementation.

nmap 7.93+dfsg1-1 (deb) pkg:deb/debian/[email protected]%2Bdfsg1-1?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=7.93+dfsg1-1 Fixed version Not Fixed EPSS Score 2.28% EPSS Percentile 90th percentile Description Nmap through 7.70, when the -sV option is used, allows remote attackers to cause a denial of service (stack consumption and application crash) via a crafted TCP-based service.

net-snmp 5.9.3+dfsg-2 (deb) pkg:deb/debian/[email protected]%2Bdfsg-2?os_distro=bookworm&os_name=debian&os_version=12 Affected range >=5.9.3+dfsg-2 Fixed version Not Fixed Description net-snmp 5.9.4 contains a memory leak vulnerability in /net-snmp/apps/snmpvacm.c.
