CVE-2025-6021 2 Redhat, Xmlsoft 20 Enterprise Linux, Enterprise Linux Eus, Enterprise Linux For Arm 64 and 17 more 2026-03-24 N/A 7.5 HIGH
A flaw was found in libxml2's xmlBuildQName function, where integer overflows in buffer size calculations can lead to a stack-based buffer overflow. This issue can result in memory corruption or a denial of service when processing crafted input.
CVE-2023-6816 4 Debian, Fedoraproject, Redhat and 1 more 7 Debian Linux, Fedora, Enterprise Linux Desktop and 4 more 2026-03-19 N/A 9.8 CRITICAL
A flaw was found in X.Org server. Both DeviceFocusEvent and the XIQueryPointer reply contain a bit for each logical button currently down. Buttons can be arbitrarily mapped to any value up to 255, but the X.Org Server was only allocating space for the device's particular number of buttons, leading to a heap overflow if a bigger value was used.
CVE-2023-5455 3 Fedoraproject, Freeipa, Redhat 21 Fedora, Freeipa, Codeready Linux Builder and 18 more 2026-03-18 N/A 6.5 MEDIUM
A Cross-site request forgery vulnerability exists in ipa/session/login_password in all supported versions of IPA. This flaw allows an attacker to trick the user into submitting a request that could perform actions as the user, resulting in a loss of confidentiality and system integrity. During community penetration testing it was found that for certain HTTP end-points FreeIPA does not ensure CSRF protection. Due to implementation details one cannot use this flaw for reflection of a cookie representing already logged-in user. An attacker would always have to go through a new authentication attempt.
CVE-2017-5848 3 Debian, Gstreamer, Redhat 8 Debian Linux, Gstreamer, Enterprise Linux Desktop and 5 more 2026-03-17 5.0 MEDIUM 7.5 HIGH
The gst_ps_demux_parse_psm function in gst/mpegdemux/gstmpegdemux.c in gst-plugins-bad in GStreamer allows remote attackers to cause a denial of service (invalid memory read and crash) via vectors involving PSM parsing.
CVE-2016-9446 3 Fedoraproject, Gstreamer, Redhat 8 Fedora, Gstreamer, Enterprise Linux Desktop and 5 more 2026-03-17 5.0 MEDIUM 7.5 HIGH
The vmnc decoder in the gstreamer does not initialize the render canvas, which allows remote attackers to obtain sensitive information as demonstrated by thumbnailing a simple 1 frame vmnc movie that does not draw to the allocated render canvas.
CVE-2015-0797 6 Debian, Gstreamer, Linux and 3 more 15 Debian Linux, Gstreamer, Linux Kernel and 12 more 2026-03-17 6.8 MEDIUM N/A
GStreamer before 1.4.5, as used in Mozilla Firefox before 38.0, Firefox ESR 31.x before 31.7, and Thunderbird before 31.7 on Linux, allows remote attackers to cause a denial of service (buffer over-read and application crash) or possibly execute arbitrary code via crafted H.264 video data in an m4v file.
CVE-2019-1125 2 Microsoft, Redhat 15 Windows 10, Windows 7, Windows 8.1 and 12 more 2026-02-20 2.1 LOW 5.6 MEDIUM
An information disclosure vulnerability exists when certain central processing units (CPU) speculatively access memory. An attacker who successfully exploited the vulnerability could read privileged data across trust boundaries. To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted application. The vulnerability would not allow an attacker to elevate user rights directly, but it could be used to obtain information that could be used to try to compromise the affected system further. On January 3, 2018, Microsoft released an advisory and security updates related to a newly-discovered class of hardware vulnerabilities (known as Spectre) involving speculative execution side channels that affect AMD, ARM, and Intel CPUs to varying degrees. This vulnerability, released on August 6, 2019, is a variant of the Spectre Variant 1 speculative execution side channel vulnerability and has been assigned CVE-2019-1125. Microsoft released a security update on July 9, 2019 that addresses the vulnerability through a software change that mitigates how the CPU speculatively accesses memory. Note that this vulnerability does not require a microcode update from your device OEM.
CVE-2018-14634 6 Canonical, F5, Linux and 3 more 28 Ubuntu Linux, Big-ip Access Policy Manager, Big-ip Advanced Firewall Manager and 25 more 2026-01-27 7.2 HIGH 7.8 HIGH
An integer overflow flaw was found in the Linux kernel's create_elf_tables() function. An unprivileged local user with access to SUID (or otherwise privileged) binary could use this flaw to escalate their privileges on the system. Kernel versions 2.6.x, 3.10.x and 4.14.x are believed to be vulnerable.
CVE-2019-3863 5 Debian, Libssh2, Netapp and 2 more 10 Debian Linux, Libssh2, Ontap Select Deploy Administration Utility and 7 more 2025-12-19 6.8 MEDIUM 7.5 HIGH
A flaw was found in libssh2 before 1.8.1 creating a vulnerability on the SSH client side. A server could send a multiple keyboard interactive response messages whose total length are greater than unsigned char max characters. This value is used by the SSH client as an index to copy memory causing in an out of bounds memory write error.
CVE-2018-15473 7 Canonical, Debian, Netapp and 4 more 24 Ubuntu Linux, Debian Linux, Aff Baseboard Management Controller and 21 more 2025-12-17 5.0 MEDIUM 5.3 MEDIUM
OpenSSH through 7.7 is prone to a user enumeration vulnerability due to not delaying bailout for an invalid authenticating user until after the packet containing the request has been fully parsed, related to auth2-gss.c, auth2-hostbased.c, and auth2-pubkey.c.
CVE-2016-1762 6 Apple, Canonical, Debian and 3 more 15 Iphone Os, Mac Os X, Safari and 12 more 2025-12-17 5.8 MEDIUM 8.1 HIGH
The xmlNextChar function in libxml2 before 2.9.4 allows remote attackers to cause a denial of service (heap-based buffer over-read) via a crafted XML document.
CVE-2016-1834 6 Apple, Canonical, Debian and 3 more 14 Iphone Os, Mac Os X, Tvos and 11 more 2025-12-04 9.3 HIGH 7.8 HIGH
