CBL Mariner 2.0 Security Update: golang / msft-golang (CVE-2025-22871)

critical Nessus Plugin ID 234633

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of golang / msft-golang installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2025-22871 advisory.

 - 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. (CVE-2025-22871)

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.
