high Nessus Plugin ID 324665

Synopsis

The remote TencentOS Server 2 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 2 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:1021 advisory.

 Package updates are available for TencentOS Server 2 that fix the following vulnerabilities:

 CVE-2023-34440:
 Improper input validation in UEFI firmware for some Intel(R) Processors may allow a privileged user to potentially enable escalation of privilege via local access.

 CVE-2023-43758:

 CVE-2024-29214:

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.
