USN-6014-1: Linux kernel vulnerabilities Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service (connection termination) or inject forged data. (CVE-2020-36516) Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information. (CVE-2021-26401) Jürgen Groß discovered that the Xen subsystem within the Linux kernel did not adequately limit the number of events driver domains (unprivileged PV backends) could send to other guest VMs. An attacker in a driver domain could use this to cause a denial of service in [ more… ]

USN-6011-1: Json-smart vulnerabilities It was discovered that Json-smart incorrectly handled memory when processing input containing unclosed quotes. A remote attacker could possibly use this issue to cause applications using Json-smart to crash, leading to a denial of service. (CVE-2021-31684) It was discovered that Json-smart incorrectly handled memory when processing input containing unclosed brackets. A remote attacker could possibly use this issue to cause applications using Json-smart to crash, leading to a denial of service. (CVE-2023-1370) Source: USN-6011-1: Json-smart vulnerabilities
