Ubuntu 12.04 LTS / 14.04 LTS / 15.10 / 16.04 LTS : expat vulnerabilities (USN-3010-1)

High Nessus Plugin ID 91726


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


It was discovered that Expat unexpectedly called srand in certain circumstances. This could reduce the security of calling applications.

It was discovered that Expat incorrectly handled seeding the random number generator. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2016-5300).

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.
