RHEL 7 : patch (RHSA-2019:3757)

high Nessus Plugin ID 130743

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for patch.

Description

The remote Redhat Enterprise Linux 7 host has a package installed that is affected by multiple vulnerabilities as referenced in the RHSA-2019:3757 advisory.

The patch program applies diff files to originals. The diff command is used to compare an original to a changed file. Diff lists the changes made to the file. A person who has the original file can then use the patch command with the diff file to add the changes to their original file (patching the file).

Security Fix(es):

* patch: do_ed_script in pch.c does not block strings beginning with a ! character (CVE-2018-20969)

* patch: OS shell command injection when processing crafted patch files (CVE-2019-13638)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

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

Solution

Update the RHEL patch package based on the guidance in RHSA-2019:3757.
