medium Nessus Plugin ID 238700

Synopsis

The remote TencentOS Server 3 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 3 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2022:0212 advisory.

 Package updates are available for TencentOS Server 3 that fix the following vulnerabilities:

 CVE-2021-0127:
 Insufficient control flow management in some Intel(R) Processors may allow an authenticated user to potentially enable a denial of service via local access.

 CVE-2021-0145:
 Improper initialization of shared resources in some Intel(R) Processors may allow an authenticated user to potentially enable information disclosure via local access.

 CVE-2021-33120:
 Out of bounds read under complex microarchitectural condition in memory subsystem for some Intel Atom(R) Processors may allow authenticated user to potentially enable information disclosure or cause denial of service via network access.

Tenable has extracted the preceding description block directly from the Tencent Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
