USN-5667-1: Linux kernel vulnerabilities Selim Enes Karaduman discovered that a race condition existed in the General notification queue implementation of the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1882) 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) Eric Biggers discovered that a use-after-free vulnerability existed in the io_uring subsystem in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-3176) It was discovered that the Netlink Transformation [ more… ]

USN-5665-1: PCRE vulnerabilities It was discovered that PCRE incorrectly handled certain regular expressions. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service. (CVE-2017-6004) It was discovered that PCRE incorrectly handled certain Unicode encoding. A remote attacker could use this issue to cause applications using PCRE to crash, resulting in a denial of service. (CVE-2017-7186) Source: USN-5665-1: PCRE vulnerabilities

USN-5666-1: OpenSSH vulnerability It was discovered that OpenSSH incorrectly handled certain helper programs. An attacker could possibly use this issue to arbitrary code execution. Source: USN-5666-1: OpenSSH vulnerability
