SUSE SLES12 Security Update : sles12sp2-docker-image (SUSE-SU-2021:4011-1)

critical Nessus Plugin ID 156048

Language:

Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 host has a package installed that is affected by a vulnerability as referenced in the SUSE- SU-2021:4011-1 advisory.

 - Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the `root` user. This vulnerability appears to be the result of a regression introduced in December of 2015. Due to the nature of this issue, systems deployed using affected versions of the Alpine Linux container which utilize Linux PAM, or some other mechanism which uses the system shadow file as an authentication database, may accept a NULL password for the `root` user. (CVE-2019-5021)

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 sles12sp2-docker-image package.
