Categoría:	Mageia Linux Local Security Checks
Título:	Mageia: Security Advisory (MGASA-2023-0244)
Resumen:	The remote host is missing an update for the 'microcode' package(s) announced via the MGASA-2023-0244 advisory.
Descripción:	Summary: The remote host is missing an update for the 'microcode' package(s) announced via the MGASA-2023-0244 advisory. Vulnerability Insight: Under specific microarchitectural circumstances, a register in 'Zen 2' CPUs may not be written to 0 correctly. This may cause data from another process and/or thread to be stored in the YMM register, which may allow an attacker to potentially access sensitive information (CVE-2023-20593, also known as Zenbleed). This update adds the microcode for Amd Epyc gen 2 cpus. Other Zen 2 based CPUs will get their microcode update at a later time when Amd has fixed and validated the microcodes, see the referenced Amd url that has info about estimated timelines for various CPUs. Affected Software/OS: 'microcode' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 4.6 CVSS Vector: AV:L/AC:L/Au:S/C:C/I:N/A:N
