USN-4587-1: iTALC vulnerabilities Nicolas Ruff discovered that iTALC had buffer overflows, divide-by-zero errors and didn’t check malloc return values. A remote attacker could use these issues to cause a denial of service or possibly execute arbitrary code. (CVE-2014-6051, CVE-2014-6052, CVE-2014-6053, CVE-2014-6054, CVE-2014-6055) Josef Gajdusek discovered that iTALC had heap-based buffer overflow vulnerabilities. A remote attacker could used these issues to cause a denial of service or possibly execute arbitrary code. (CVE-2016-9941, CVE-2016-9942) It was discovered that iTALC had an out-of-bounds write, multiple heap out-of-bounds writes, an infinite loop, improper initializations, and null pointer vulnerabilities. A remote attacker could used these issues to cause a denial of service or possibly execute arbitrary code. (CVE-2018-15127, CVE-2018-20019, CVE-2018-20020, CVE-2018-20021, CVE-2018-20022, CVE-2018-20023, CVE-2018-20024, CVE-2018-20748, CVE-2018-20749, CVE-2018-20750, CVE-2018-7225, CVE-2019-15681) Source: USN-4587-1: iTALC vulnerabilities

USN-4586-1: PHP ImageMagick vulnerability It was discovered that PHP ImageMagick extension didn’t check the address used by an array. An attacker could use this issue to cause PHP ImageMagick to crash, resulting in a denial of service. Source: USN-4586-1: PHP ImageMagick vulnerability

USN-4593-1: FreeType vulnerability Sergei Glazunov discovered that FreeType did not correctly handle certain malformed font files. If a user were tricked into using a specially crafted font file, a remote attacker could cause FreeType to crash or possibly execute arbitrary code with user privileges.

USN-4592-1: Linux kernel vulnerabilities Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-confusion error. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-12351) Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate remote attacker could use this to expose sensitive information (kernel memory). (CVE-2020-12352) Andy Nguyen discovered that the Bluetooth HCI event packet parser in the Linux kernel did not properly handle event advertisements of certain sizes, leading to a heap-based buffer overflow. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-24490) Source: USN-4592-1: Linux kernel vulnerabilities

USN-4591-1: Linux kernel vulnerabilities Andy Nguyen discovered that the Bluetooth L2CAP implementation in the Linux kernel contained a type-confusion error. A physically proximate remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2020-12351) Andy Nguyen discovered that the Bluetooth A2MP implementation in the Linux kernel did not properly initialize memory in some situations. A physically proximate remote attacker could use this to expose sensitive information (kernel memory). (CVE-2020-12352) Source: USN-4591-1: Linux kernel vulnerabilities
