CBL Mariner 2.0 Security Update: libcap (CVE-2025-1390)

medium Nessus Plugin ID 216893

Synopsis

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

Description

The version of libcap 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-2025-1390 advisory.

 - The PAM module pam_cap.so of libcap configuration supports group names starting with @, during actual parsing, configurations not starting with @ are incorrectly recognized as group names. This May result in nonintended users being granted an inherited capability set, potentially leading to security risks.
 Attackers can exploit this vulnerability to achieve local privilege escalation on systems where /etc/security/capability.conf is used to configure user inherited privileges by constructing specific usernames. (CVE-2025-1390)

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.
