Bugs fixed (https://bugzilla.redhat.com/): 2107342 - CVE-2022-30631 golang: compress/gzip: stack exhaustion in Reader.Read 5. ========================================================================== Ubuntu Security Notice USN-5535-1 July 28, 2022 Intel Microcode vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 ESM Summary: Several security issues were fixed in Intel Microcode. Software Description: - intel-microcode: Processor microcode for Intel CPUs Details: Joseph Nuzman discovered that some Intel processors did not properly initialise shared resources. A local attacker could use this to obtain sensitive information. (CVE-2021-0145) Mark Ermolov, Dmitry Sklyarov and Maxim Goryachy discovered that some Intel processors did not prevent test and debug logic from being activated at runtime. A local attacker could use this to escalate privileges. (CVE-2021-0146) It was discovered that some Intel processors did not implement sufficient control flow management. A local attacker could use this to cause a denial of service (system crash). (CVE-2021-0127) It was discovered that some Intel processors did not completely perform cleanup actions on multi-core shared buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21123, CVE-2022-21127) It was discovered that some Intel processors did not completely perform cleanup actions on microarchitectural fill buffers. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21125) Alysa Milburn, Jason Brandt, Avishai Redelman and Nir Lavi discovered that some Intel processors improperly optimised security-critical code. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21151) It was discovered that some Intel processors did not properly perform cleanup during specific special register write operations. A local attacker could possibly use this to expose sensitive information. (CVE-2022-21166) It was discovered that some Intel processors did not properly restrict access in some situations. A local attacker could use this to obtain sensitive information. (CVE-2021-33117) Brandon Miller discovered that some Intel processors did not properly restrict access in some situations. A local attacker could use this to obtain sensitive information or a remote attacker could use this to cause a denial of service (system crash). (CVE-2021-33120) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: intel-microcode 3.20220510.0ubuntu0.16.04.1+esm1 In general, a standard system update will make all the necessary changes
