Ubuntu 12.04 LTS / 14.04 LTS / 15.04 : expat vulnerability (USN-2726-1)

Medium Nessus Plugin ID 85724


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


It was 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.

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.


Update the affected lib64expat1 and / or libexpat1 packages.
