TencentOS Server 4: sudo (TSSA-2025:0513)

high Nessus Plugin ID 241458

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2025:0513 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2025-32463:
Sudo before 1.9.17p1 allows local users to obtain root access because /etc/nsswitch.conf from a user- controlled directory is used with the --chroot option.

CVE-2025-32462:
Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host nor ALL, allows listed users to execute commands on unintended machines.

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.

Solution

Update the affected packages.
