Azure Linux 3.0 Security Update: CBL-Mariner Releases (CVE-2026-39828)

medium Nessus Plugin ID 318148

Language:

Synopsis

The remote Azure Linux host is missing one or more security updates.

Description

The version of CBL-Mariner Releases installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2026-39828 advisory.

- When an SSH server authentication callback returned PartialSuccessError with non-nil Permissions, those permissions were silently discarded, potentially dropping certificate restrictions such as force-command after a second factor succeeded. Returning non-nil Permissions with PartialSuccessError now results in a connection error. (CVE-2026-39828)

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.
