USN-5361-1: Linux kernel vulnerabilities It was discovered that the VFIO PCI driver in the Linux kernel did not properly handle attempts to access disabled memory spaces. A local attacker could use this to cause a denial of service (system crash). (CVE-2020-12888) Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation did not properly verify certain fragmented frames. A physically proximate attacker could possibly use this issue to inject or decrypt packets. (CVE-2020-26141) Mathy Vanhoef discovered that the Linux kernel’s WiFi implementation accepted plaintext fragments in certain situations. A physically proximate attacker could use this issue to inject packets. (CVE-2020-26145) It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information (WiFi network traffic). (CVE-2020-3702) It was discovered a race condition existed in the [ more… ]

USN-5358-2: Linux kernel vulnerabilities It was discovered that the network traffic control implementation in the Linux kernel contained 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-2022-1055) It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-27666) Source: USN-5358-2: Linux kernel vulnerabilities

USN-5357-2: Linux kernel vulnerability It was discovered that the IPsec implementation in the Linux kernel did not properly allocate enough memory when performing ESP transformations, leading to a heap-based buffer overflow. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Source: USN-5357-2: Linux kernel vulnerability

USN-5360-1: Tomcat vulnerabilities It was discovered that Tomcat incorrectly performed input verification. A remote attacker could possibly use this issue to intercept sensitive information. (CVE-2020-13943, CVE-2020-17527, CVE-2021-25122, CVE-2021-30640) It was discovered that Tomcat did not properly deserialize untrusted data. An attacker could possibly use this issue to execute arbitrary code. (CVE-2020-9484, CVE-2021-33037) It was discovered that Tomcat did not properly validate the input length. An attacker could possibly use this to trigger an infinite loop, resulting in a denial of service. (CVE-2020-9494, CVE-2021-25329, CVE-2021-41079) Source: USN-5360-1: Tomcat vulnerabilities

USN-5359-1: rsync vulnerability Danilo Ramos discovered that rsync incorrectly handled memory when performing certain zlib deflating operations. An attacker could use this issue to cause rsync to crash, resulting in a denial of service, or possibly execute arbitrary code. Source: USN-5359-1: rsync vulnerability
