CVE-2009-3555 9 Apache, Canonical, Debian and 6 more 15 Http Server, Ubuntu Linux, Debian Linux and 12 more 2026-05-27 9.8 Critical
The TLS protocol, and the SSL protocol 3.0 and possibly earlier, as used in Microsoft Internet Information Services (IIS) 7.0, mod_ssl in the Apache HTTP Server 2.2.14 and earlier, OpenSSL before 0.9.8l, GnuTLS 2.8.5 and earlier, Mozilla Network Security Services (NSS) 3.12.4 and earlier, multiple Cisco products, and other products, does not properly associate renegotiation handshakes with an existing connection, which allows man-in-the-middle attackers to insert data into HTTPS sessions, and possibly other types of sessions protected by TLS or SSL, by sending an unauthenticated request that is processed retroactively by a server in a post-renegotiation context, related to a "plaintext injection" attack, aka the "Project Mogul" issue.
CVE-2015-8325 4 Canonical, Debian, Openbsd and 1 more 6 Ubuntu Core, Ubuntu Linux, Ubuntu Touch and 3 more 2026-05-22 7.8 High
The do_setup_env function in session.c in sshd in OpenSSH through 7.2p2, when the UseLogin feature is enabled and PAM is configured to read .pam_environment files in user home directories, allows local users to gain privileges by triggering a crafted environment for the /bin/login program, as demonstrated by an LD_PRELOAD environment variable.
CVE-2013-2566 4 Canonical, Fujitsu, Mozilla and 1 more 24 Ubuntu Linux, M10-1, M10-1 Firmware and 21 more 2026-05-22 5.9 Medium
The RC4 algorithm, as used in the TLS protocol and SSL protocol, has many single-byte biases, which makes it easier for remote attackers to conduct plaintext-recovery attacks via statistical analysis of ciphertext in a large number of sessions that use the same plaintext.
CVE-2023-4911 7 Canonical, Debian, Fedoraproject and 4 more 51 Ubuntu Linux, Debian Linux, Fedora and 48 more 2026-05-12 7.8 High
A buffer overflow was discovered in the GNU C Library's dynamic loader ld.so while processing the GLIBC_TUNABLES environment variable. This issue could allow a local attacker to use maliciously crafted GLIBC_TUNABLES environment variables when launching binaries with SUID permission to execute code with elevated privileges.
CVE-2018-25306 2 Canonical, Poppler-utils 2 Pdfunite, Pdfunite 2026-05-05 6.2 Medium
PDFunite 0.41.0 contains a buffer overflow vulnerability that allows local attackers to crash the application by processing malformed PDF files during merge operations. Attackers can trigger a segmentation fault in the XRef::getEntry function within libpoppler by providing a specially crafted PDF file to the pdfunite utility.
CVE-2026-5412 1 Canonical 1 Juju 2026-04-30 9.9 Critical
In Juju versions prior to 2.9.57 and 3.6.21, an authorization issue exists in the Controller facade. An authenticated user can call the CloudSpec API method to extract the cloud credentials used to bootstrap the controller. This allows a low-privileged user to access sensitive credentials. This issue is resolved in Juju versions 2.9.57 and 3.6.21.
CVE-2018-17958 4 Canonical, Debian, Qemu and 1 more 8 Ubuntu Linux, Debian Linux, Qemu and 5 more 2026-04-28 7.5 High
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used.
CVE-2016-10708 5 Canonical, Debian, Netapp and 2 more 13 Ubuntu Linux, Debian Linux, Cloud Backup and 10 more 2026-04-28 7.5 High
sshd in OpenSSH before 7.4 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via an out-of-sequence NEWKEYS message, as demonstrated by Honggfuzz, related to kex.c and packet.c.
CVE-2026-6970 1 Canonical 1 Authd 2026-04-28 N/A
authd prior to version 0.6.4 contains a logic error in primary group ID assignment that can lead to local privilege escalation. When a user's primary group ID (GID) differs from their UID, either because the account was created with authd prior to version 0.5.4 or because the primary group was manually changed via the `authctl group set-gid` command, and the user's identity provider record is updated, authd incorrectly resets the user's primary group ID to their UID upon next login. This causes newly created files and directories to be owned by the wrong group, causing denial of service issues, and potentially granting unintended access to other local users and allowing local privilege escalation.
CVE-2006-6811 2 Canonical, Kde 2 Ubuntu Linux, Ksirc 2026-04-23 6.5 Medium
KsIRC 1.3.12 allows remote attackers to cause a denial of service (crash) via a long PRIVMSG string when connecting to an Internet Relay Chat (IRC) server, which causes an assertion failure and results in a NULL pointer dereference. NOTE: this issue was originally reported as a buffer overflow.
CVE-2009-3620 6 Canonical, Fedoraproject, Linux and 3 more 11 Ubuntu Linux, Fedora, Linux Kernel and 8 more 2026-04-23 7.8 High
The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.
CVE-2009-3001 2 Canonical, Linux 2 Ubuntu Linux, Linux Kernel 2026-04-23 N/A
The llc_ui_getname function in net/llc/af_llc.c in the Linux kernel 2.6.31-rc7 and earlier does not initialize a certain data structure, which allows local users to read the contents of some kernel memory locations by calling getsockname on an AF_LLC socket.
CVE-2007-3387 7 Apple, Canonical, Debian and 4 more 7 Cups, Ubuntu Linux, Debian Linux and 4 more 2026-04-23 N/A
Integer overflow in the StreamPredictor::StreamPredictor function in xpdf 3.02, as used in (1) poppler before 0.5.91, (2) gpdf before 2.8.2, (3) kpdf, (4) kdegraphics, (5) CUPS, (6) PDFedit, and other products, might allow remote attackers to execute arbitrary code via a crafted PDF file that triggers a stack-based buffer overflow in the StreamPredictor::getNextLine function.
CVE-2009-2906 3 Canonical, Redhat, Samba 4 Ubuntu Linux, Enterprise Linux, Rhel Extras and 1 more 2026-04-23 N/A
smbd in Samba 3.0 before 3.0.37, 3.2 before 3.2.15, 3.3 before 3.3.8, and 3.4 before 3.4.2 allows remote authenticated users to cause a denial of service (infinite loop) via an unanticipated oplock break notification reply packet.
CVE-2008-3275 5 Canonical, Debian, Linux and 2 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2026-04-23 5.5 Medium
The (1) real_lookup and (2) __lookup_hash functions in fs/namei.c in the vfs implementation in the Linux kernel before 2.6.25.15 do not prevent creation of a child dentry for a deleted (aka S_DEAD) directory, which allows local users to cause a denial of service ("overflow" of the UBIFS orphan area) via a series of attempted file creations within deleted directories.
CVE-2008-3272 4 Canonical, Debian, Linux and 1 more 9 Ubuntu Linux, Debian Linux, Linux Kernel and 6 more 2026-04-23 N/A
The snd_seq_oss_synth_make_info function in sound/core/seq/oss/seq_oss_synth.c in the sound subsystem in the Linux kernel before 2.6.27-rc2 does not verify that the device number is within the range defined by max_synthdev before returning certain data to the caller, which allows local users to obtain sensitive information.
CVE-2008-1721 4 Canonical, Debian, Python and 1 more 4 Ubuntu Linux, Debian Linux, Python and 1 more 2026-04-23 N/A
Integer signedness error in the zlib extension module in Python 2.5.2 and earlier allows remote attackers to execute arbitrary code via a negative signed integer, which triggers insufficient memory allocation and a buffer overflow.
CVE-2007-4772 5 Canonical, Debian, Postgresql and 2 more 6 Ubuntu Linux, Debian Linux, Postgresql and 3 more 2026-04-23 N/A
The regular expression parser in TCL before 8.4.17, as used in PostgreSQL 8.2 before 8.2.6, 8.1 before 8.1.11, 8.0 before 8.0.15, and 7.4 before 7.4.19, allows context-dependent attackers to cause a denial of service (infinite loop) via a crafted regular expression.
CVE-2007-2172 4 Canonical, Debian, Linux and 1 more 4 Ubuntu Linux, Debian Linux, Linux Kernel and 1 more 2026-04-23 N/A
A typo in Linux kernel 2.6 before 2.6.21-rc6 and 2.4 before 2.4.35 causes RTA_MAX to be used as an array size instead of RTN_MAX, which leads to an "out of bound access" by the (1) dn_fib_props (dn_fib.c, DECNet) and (2) fib_props (fib_semantics.c, IPv4) functions.
CVE-2007-1864 4 Canonical, Debian, Php and 1 more 7 Ubuntu Linux, Debian Linux, Php and 4 more 2026-04-23 N/A
Buffer overflow in the bundled libxmlrpc library in PHP before 4.4.7, and 5.x before 5.2.2, has unknown impact and remote attack vectors.
