Synopsis

The remote Fedora host is missing one or more security updates.

Description

The remote Fedora 37 host has a package installed that is affected by multiple vulnerabilities as referenced in the FEDORA-2023-b28dc472b0 advisory.

 - 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)

 - 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)

 - 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)

 - 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.
