Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLES15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2021:3256-1 advisory.

- A flaw was found in postgresql. A purpose-crafted query can read arbitrary bytes of server memory. In the default configuration, any authenticated database user can complete this attack at will. The attack does not require the ability to create objects. If server settings include max_worker_processes=0, the known versions of this attack are infeasible. However, undiscovered variants of the attack may be independent of that setting. (CVE-2021-3677)

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.
