critical Nessus Plugin ID 241480

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-2025:0497 advisory.

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

 CVE-2025-22871:
 The net/http package improperly accepts a bare LF as a line terminator in chunked data chunk-size lines.
 This can permit request smuggling if a net/http server is used in conjunction with a server that incorrectly accepts a bare LF as part of a chunk-ext.

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.
