CBL Mariner 2.0 Security Update: shadow-utils (CVE-2023-4641)

medium Nessus Plugin ID 235318

Synopsis

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

Description

The version of shadow-utils 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-2023-4641 advisory.

 - A flaw was found in shadow-utils. When asking for a new password, shadow-utils asks the password twice. If the password fails on the second attempt, shadow-utils fails in cleaning the buffer used to store the first entry. This May allow an attacker with enough access to retrieve the password from the memory.
 (CVE-2023-4641)

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.
