Synopsis

The remote Red Hat host is missing a security update for augeas.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2788 advisory.

Augeas is a configuration editing tool. It parses configuration files in their native formats and transforms them into a tree. Configuration changes are made by manipulating this tree and saving it back into native config files.

Security Fix(es):

* A vulnerability was discovered in augeas affecting the handling of escaped strings. An attacker could send crafted strings that would cause the application using augeas to copy past the end of a buffer, leading to a crash or possible code execution. (CVE-2017-7555)

This issue was discovered by Han Han (Red Hat).

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

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 RHEL augeas package based on the guidance in RHSA-2017:2788.
