CVE-2015-4000 13 Apple, Canonical, Debian and 10 more 31 Iphone Os, Mac Os X, Safari and 28 more 2026-05-27 3.7 Low
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
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-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.
CVE-2007-1667 4 Canonical, Debian, Redhat and 1 more 4 Ubuntu Linux, Debian Linux, Enterprise Linux and 1 more 2026-04-23 N/A
Multiple integer overflows in (1) the XGetPixel function in ImUtil.c in X.Org libx11 before 1.0.3, and (2) XInitImage function in xwd.c for ImageMagick, allow user-assisted remote attackers to cause a denial of service (crash) or obtain sensitive information via crafted images with large or negative values that trigger a buffer overflow.
CVE-2008-2931 6 Canonical, Debian, Linux and 3 more 7 Ubuntu Linux, Debian Linux, Linux Kernel and 4 more 2026-04-23 7.8 High
The do_change_type function in fs/namespace.c in the Linux kernel before 2.6.22 does not verify that the caller has the CAP_SYS_ADMIN capability, which allows local users to gain privileges or cause a denial of service by modifying the properties of a mountpoint.
CVE-2007-1562 3 Canonical, Mozilla, Redhat 3 Ubuntu Linux, Firefox, Enterprise Linux 2026-04-23 N/A
The FTP protocol implementation in Mozilla Firefox before 1.5.0.11 and 2.x before 2.0.0.3 allows remote attackers to force the client to connect to other servers, perform a proxied port scan, or obtain sensitive information by specifying an alternate server address in an FTP PASV response.
CVE-2007-1349 3 Apache, Canonical, Redhat 12 Mod Perl, Ubuntu Linux, Certificate System and 9 more 2026-04-23 N/A
PerlRun.pm in Apache mod_perl before 1.30, and RegistryCooker.pm in mod_perl 2.x, does not properly escape PATH_INFO before use in a regular expression, which allows remote attackers to cause a denial of service (resource consumption) via a crafted URI.
CVE-2008-2829 2 Canonical, Php 2 Ubuntu Linux, Php 2026-04-23 N/A
php_imap.c in PHP 5.2.5, 5.2.6, 4.x, and other versions, uses obsolete API calls that allow context-dependent attackers to cause a denial of service (crash) and possibly execute arbitrary code via a long IMAP request, which triggers an "rfc822.c legacy routine buffer overflow" error message, related to the rfc822_write_address function.
CVE-2008-2934 3 Apple, Canonical, Mozilla 3 Mac Os X, Ubuntu Linux, Firefox 2026-04-23 8.8 High
Mozilla Firefox 3 before 3.0.1 on Mac OS X allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted GIF file that triggers a free of an uninitialized pointer.
CVE-2007-1285 5 Canonical, Novell, Php and 2 more 10 Ubuntu Linux, Suse Linux, Php and 7 more 2026-04-23 7.5 High
The Zend Engine in PHP 4.x before 4.4.7, and 5.x before 5.2.2, allows remote attackers to cause a denial of service (stack exhaustion and PHP crash) via deeply nested arrays, which trigger deep recursion in the variable destruction routines.
CVE-2007-1216 4 Canonical, Debian, Mit and 1 more 4 Ubuntu Linux, Debian Linux, Kerberos 5 and 1 more 2026-04-23 N/A
Double free vulnerability in the GSS-API library (lib/gssapi/krb5/k5unseal.c), as used by the Kerberos administration daemon (kadmind) in MIT krb5 before 1.6.1, when used with the authentication method provided by the RPCSEC_GSS RPC library, allows remote authenticated users to execute arbitrary code and modify the Kerberos key database via a message with an "an invalid direction encoding".
CVE-2008-2812 8 Avaya, Canonical, Debian and 5 more 16 Communication Manager, Expanded Meet-me Conferencing, Intuity Audix Lx and 13 more 2026-04-23 7.8 High
The Linux kernel before 2.6.25.10 does not properly perform tty operations, which allows local users to cause a denial of service (system crash) or possibly gain privileges via vectors involving NULL pointer dereference of function pointers in (1) hamradio/6pack.c, (2) hamradio/mkiss.c, (3) irda/irtty-sir.c, (4) ppp_async.c, (5) ppp_synctty.c, (6) slip.c, (7) wan/x25_asy.c, and (8) wireless/strip.c in drivers/net/.
