USN-5887-1: ClamAV vulnerabilities Simon Scannell discovered that ClamAV incorrectly handled parsing HFS+ files. A remote attacker could possibly use this issue to cause ClamAV to crash, resulting in a denial of service, or execute arbitrary code. (CVE-2023-20032) Simon Scannell discovered that ClamAV incorrectly handled parsing DMG files. A remote attacker could possibly use this issue to expose sensitive information. (CVE-2023-20052) Source: USN-5887-1: ClamAV vulnerabilities

USN-5886-1: Intel Microcode vulnerabilities Erik C. Bjorge discovered that some Intel(R) Atom and Intel Xeon Scalable Processors did not properly implement access controls for out-of-band management. This may allow a privileged network-adjacent user to potentially escalate privileges. (CVE-2022-21216) Cfir Cohen, Erdem Aktas, Felix Wilhelm, James Forshaw, Josh Eads, Nagaraju Kodalapura Nagabhushana Rao, Przemyslaw Duda, Liron Shacham and Ron Anderson discovered that some Intel(R) Xeon(R) Processors used incorrect default permissions in some memory controller configurations when using Intel(R) Software Guard Extensions. This may allow a privileged local user to potentially escalate privileges. (CVE-2022-33196) It was discovered that some 3rd Generation Intel(R) Xeon(R) Scalable Processors did not properly calculate microkey keying. This may allow a privileged local user to potentially disclose information. (CVE-2022-33972) Joseph Nuzman discovered that some Intel(R) Processors when using Intel(R) Software Guard Extensions did not properly isolate shared resources. [ more… ]

USN-5885-1: APR vulnerability Ronald Crane discovered integer overflow vulnerabilities in the Apache Portable Runtime (APR) that could potentially result in memory corruption. A remote attacker could possibly use these issues to cause a denial of service or execute arbitary code. Source: USN-5885-1: APR vulnerability

USN-5884-1: Linux kernel (AWS) vulnerabilities Kirill Tkhai discovered that the XFS file system implementation in the Linux kernel did not calculate size correctly when pre-allocating space in some situations. A local attacker could use this to expose sensitive information. (CVE-2021-4155) Lee Jones discovered that a use-after-free vulnerability existed in the Bluetooth implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20566) Duoming Zhou discovered that a race condition existed in the SLIP driver in the Linux kernel, leading to a null pointer dereference vulnerability. An attacker could use this to cause a denial of service (system crash). (CVE-2022-41858) Tamás Koczka discovered that the Bluetooth L2CAP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate attacker could possibly use [ more… ]

USN-5883-1: Linux kernel (HWE) vulnerabilities Kyle Zeng discovered that the sysctl implementation in the Linux kernel contained a stack-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-4378) It was discovered that an out-of-bounds write vulnerability existed in the Video for Linux 2 (V4L2) implementation in the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-20369) Pawan Kumar Gupta, Alyssa Milburn, Amit Peled, Shani Rehana, Nir Shildan and Ariel Sabba discovered that some Intel processors with Enhanced Indirect Branch Restricted Speculation (eIBRS) did not properly handle RET instructions after a VM exits. A local attacker could potentially use this to expose sensitive information. (CVE-2022-26373) David Leadbeater discovered that the netfilter IRC protocol tracking implementation in [ more… ]
