USN-4417-1: NSS vulnerability Cesar Pereida, Billy Bob Brumley, Yuval Yarom, and Nicola Tuveri discovered that NSS incorrectly handled RSA key generation. A local attacker could possibly use this issue to perform a timing attack and recover RSA keys. Source: USN-4417-1: NSS vulnerability

USN-4415-1: coTURN vulnerabilities Felix Dörre discovered that coTURN response buffer is not initialized properly. An attacker could possibly use this issue to obtain sensitive information. (CVE-2020-4067) It was discovered that coTURN web server incorrectly handled HTTP POST requests. An attacker could possibly use this issue to cause a denial of service, obtain sensitive information or other unspecified impact. (CVE-2020-6061, CVE-2020-6062) Source: USN-4415-1: coTURN vulnerabilities

USN-4416-1: GNU C Library vulnerabilities Florian Weimer discovered that the GNU C Library incorrectly handled certain memory operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-12133) It was discovered that the GNU C Library incorrectly handled certain SSE2-optimized memmove operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This issue only affected Ubuntu 16.04 LTS. (CVE-2017-18269) It was discovered that the GNU C Library incorrectly handled certain pathname operations. A remote attacker could use this issue to cause the GNU C Library to crash, resulting in a denial of service, or possibly execute arbitrary code. This [ more… ]

USN-4419-1: Linux kernel vulnerabilities It was discovered that a race condition existed in the Precision Time Protocol (PTP) implementation in the Linux kernel, leading to a use-after- free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-10690) Matthew Sheets discovered that the SELinux network label handling implementation in the Linux kernel could be coerced into de-referencing a NULL pointer. A remote attacker could use this to cause a denial of service (system crash). (CVE-2020-10711) It was discovered that the DesignWare SPI controller driver in the Linux kernel contained a race condition. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2020-12769) It was discovered that the SCSI generic (sg) driver in the Linux kernel did not properly handle certain error conditions [ more… ]
