Ubuntu 12.04 LTS / 14.04 LTS / 15.10 / 16.04 LTS : expat vulnerability (USN-2983-1)

High Nessus Plugin ID 91259

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Gustavo Grieco discovered that Expat incorrectly handled malformed XML data. If a user or application linked against Expat were tricked into opening a crafted XML file, an attacker could cause a denial of service, or possibly execute arbitrary code. (CVE-2016-0718).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected lib64expat1 and / or libexpat1 packages.
