Ubuntu 10.04 LTS / 12.04 LTS / 12.10 / 13.10 : nspr vulnerability (USN-2087-1)

High Nessus Plugin ID 72115


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


It was discovered that NSPR incorrectly handled certain malformed X.509 certificates. A remote attacker could use a crafted X.509 certificate to cause NSPR to crash, leading to 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 libnspr4 and / or libnspr4-0d packages.
