An issue has been discovered in GitLab affecting all versions starting from 15.2 before 16.0.8, all versions starting from 16.1 before 16.1.3, all versions starting from 16.2 before 16.2.2. A Regular Expression Denial of Service was possible by using crafted payloads to search Harbor Registry.

An issue has been discovered in GitLab CE/EE affecting all versions starting from 8.14 before 16.0.8, all versions starting from 16.1 before 16.1.3, all versions starting from 16.2 before 16.2.2. A Regular Expression Denial of Service was possible via sending crafted payloads which use AutolinkFilter to the preview_markdown endpoint.

A buffer overflow vulnerability in “diagstatus” command in Brocade Fabric OS before Brocade Fabric v9.2.0 and v9.1.1c could allow an authenticated user to crash the Brocade Fabric OS switch leading to a denial of service.

A set of carefully crafted ipv6 packets can trigger an integer overflow in the calculation of a fragment reassembled packet's payload length field. This allows an attacker to trigger a kernel panic, resulting in a denial of service.

### Impact Keylime `registrar` is prone to a simple denial of service attack in which an adversary opens a connection to the TLS port (by default, port `8891`) blocking further, legitimate connections. As long as the connection is open, the `registrar` is blocked and cannot serve any further clients (`agents` and `tenants`), which prevents normal operation. The problem does not affect the `verifier`. ### Patches Users should upgrade to release 7.4.0

Those using Jettison to parse untrusted XML or JSON data may be vulnerable to Denial of Service attacks (DOS). If the parser is running on user supplied input, an attacker may supply content that causes the parser to crash by stackoverflow. This effect may support a denial of service attack. ### References - https://nvd.nist.gov/vuln/detail/CVE-2022-40149 - https://github.com/jettison-json/jettison/issues/45 - https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=46538 - https://github.com/jettison-json/jettison/pull/49/files - https://github.com/jettison-json/jettison/releases/tag/jettison-1.5.1 - https://lists.debian.org/debian-lts-announce/2022/11/msg00011.html - https://www.debian.org/security/2023/dsa-5312

A buffer overflow flaw was found in base/gdevdevn.c:1973 in devn_pcx_write_rle() in ghostscript. This issue may allow a local attacker to cause a denial of service via outputting a crafted PDF file for a DEVN device with gs.

An integer overflow flaw was found in pcl/pl/plfont.c:418 in pl_glyph_name in ghostscript. This issue may allow a local attacker to cause a denial of service via transforming a crafted PCL file to PDF format.

Ubuntu Security Notice 6263-1 - Motoyasu Saburi discovered that OpenJDK incorrectly handled special characters in file name parameters. An attacker could possibly use this issue to insert, edit or obtain sensitive information. This issue only affected OpenJDK 11 and OpenJDK 17. Eirik Bjørsnøs discovered that OpenJDK incorrectly handled certain ZIP archives. An attacker could possibly use this issue to cause a denial of service. This issue only affected OpenJDK 11 and OpenJDK 17.

Ubuntu Security Notice 6264-1 - Several security issues were discovered in the WebKitGTK Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution.
