TencentOS Server 3: device-mapper-multipath (TSSA-2023:0147)

high Nessus Plugin ID 238716

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 a vulnerability as referenced in the TSSA-2023:0147 advisory.

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

 CVE-2022-41973:
 A vulnerability was found in the device-mapper-multipath. The device-mapper-multipath allows local users to obtain root access, in conjunction with CVE-2022-41974. Local users that are able to access /dev/shm can change symlinks in multipathd due to incorrect symlink handling, which may lead to controlled file writes outside of the /dev/shm directory. This could be used indirectly for local privilege escalation to root.

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

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

Solution

Update the affected packages.
