CBL Mariner 2.0 Security Update: patch (CVE-2018-20969)

high Nessus Plugin ID 201836

Synopsis

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

Description

The version of patch 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-2018-20969 advisory.

 - do_ed_script in pch.c in GNU patch through 2.7.6 does not block strings beginning with a ! character.
 NOTE: this is the same commit as for CVE-2019-13638, but the ! syntax is specific to ed, and is unrelated to a shell metacharacter. (CVE-2018-20969)

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.
