Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2023:4027-1 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.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
