RHEL 6 / 7 : expat (RHSA-2016:2824)

critical Nessus Plugin ID 95381

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2016:2824 advisory.

Expat is a C library for parsing XML documents.

Security Fix(es):

* An out-of-bounds read flaw was found in the way Expat processed certain input. A remote attacker could send specially crafted XML that, when parsed by an application using the Expat library, would cause that application to crash or, possibly, execute arbitrary code with the permission of the user running the application. (CVE-2016-0718)

Red Hat would like to thank Gustavo Grieco for reporting this issue.

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 expat package based on the guidance in RHSA-2016:2824.
