USN-5560-2: Linux kernel vulnerabilities Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not properly remove all references to a route filter before freeing it in some situations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2588) It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2586) It was discovered that the block layer subsystem in the Linux kernel did not properly initialize memory in some situations. A privileged local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-0494) Hu Jiahui discovered that [ more… ]

USN-5561-1: GNOME Web vulnerabilities It was discovered that GNOME Web incorrectly filtered certain strings. A remote attacker could use this issue to perform cross-site scripting (XSS) attacks. This issue only affected Ubuntu 20.04 LTS. (CVE-2021-45085, CVE-2021-45086, CVE-2021-45087) It was discovered that GNOME Web incorrectly handled certain long page titles. A remote attacker could use this issue to cause GNOME Web to crash, resulting in a denial of service, or possibly execute arbitrary code.

USN-5559-1: Moment.js vulnerabilities It was discovered that Moment.js incorrectly handled certain input paths. An attacker could possibly use this issue to cause a loss of integrity by changing the correct path to one of their choice. (CVE-2022-24785) It was discovered that Moment.js incorrectly handled certain input. An attacker could possibly use this issue to cause a denial of service. (CVE-2022-31129) Source: USN-5559-1: Moment.js vulnerabilities

USN-5558-1: libcdio vulnerabilities Zhao Liang discovered that libcdio was not properly performing memory management operations when processing ISO files, which could result in a heap buffer overflow or in a NULL pointer dereference. If a user or automated system were tricked into opening a specially crafted file, an attacker could possibly use this issue to cause a denial of service. (CVE-2017-18198, CVE-2017-18199) Source: USN-5558-1: libcdio vulnerabilities
