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 a vulnerability as referenced in the TSSA-2025:0539 advisory.

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

CVE-2025-4565:
Any project that uses Protobuf Pure-Python backendto parse untrusted Protocol Buffers data containing an arbitrary number of recursive groups, recursive messages or a series of SGROUPtags can be corrupted by exceeding the Python recursion limit. This can result in a Denial of service by crashing the application with a RecursionError. We recommend upgrading to version =>6.31.1 or beyond commit17838beda2943d08b8a9d4df5b68f5f04f26d901

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.
