Updated microcode packages fix security vulnerabilities


This update provides the Intel 20191112 microcode release that adds the microcode side fixes and mitigations for at least the following security issues: A flaw was found in the implementation of SGX around the access control of protected memory. A local attacker of a system with SGX enabled and an affected intel GPU with the ability to execute code is able to infer the contents of the SGX protected memory (CVE-2019-0117). TSX Asynchronous Abort condition on some CPUs utilizing speculative execution may allow an authenticated user to potentially enable information disclosure via a side channel with local access. (CVE-2019-11135). Improper conditions check in the voltage modulation interface for some Intel(R) Xeon(R) Scalable Processors may allow a privileged user to potentially enable denial of service via local access (CVE-2019-11139). Improper invalidation for page table updates by a virtual guest operating system for multiple Intel(R) Processors may allow an authenticated user to potentially enable denial of service of the host system via local access (CVE-2018-12207). TA Indirect Sharing Erratum (Information Leak) Incomplete fixes for previous MDS mitigations (VERW) SHUF* instruction implementation flaw (DoS) EGETKEY Erratum Conditional Jump Macro-fusion (DoS or Privilege Escalation) For the software side fixes and mitigations of theese issues, the kernel must be updated to 5.3.13-1.mga7 (mga¤25686) or later.
