MGASA-2023-0085 - Updated microcode packages fix security vulnerabilities

Publication date: 11 Mar 2023
URL: https://advisories.mageia.org/MGASA-2023-0085.html
Type: security
Affected Mageia releases: 8
CVE: CVE-2022-21216,
     CVE-2022-33196,
     CVE-2022-33972,
     CVE-2022-38090

Description:
Updated microcode packages fix security vulnerabilities:

Insufficient granularity of access control in out-of-band management
in some Intel(R) Atom and Intel Xeon Scalable Processors may allow a
privileged user to potentially enable escalation of privilege via
adjacent network access (CVE-2022-21216 / intel-sa-00700).

Incorrect default permissions in some memory controller configurations
for some Intel(R) Xeon(R) Processors when using Intel(R) Software Guard
Extensions which may allow a privileged user to potentially enable
escalation of privilege via local access (CVE-2022-33196 / intel-sa-00738).

Incorrect calculation in microcode keying mechanism for some 3rd
Generation Intel(R) Xeon(R) Scalable Processors may allow a privileged
user to potentially enable information disclosure via local access
(CVE-2022-33972 / intel-sa-00730).

Improper isolation of shared resources in some Intel(R) Processors when
using Intel(R) Software Guard Extensions may allow a privileged user to
potentially enable information disclosure via local access
(CVE-2022-38090 / intel-sa-00767).
