Ubuntu 10.04 LTS / 12.04 LTS / 14.04 LTS : nss vulnerability (USN-2343-1)

Critical Nessus Plugin ID 77601


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


Tyson Smith and Jesse Schwartzentruber discovered that NSS contained a race condition when performing certificate validation. An attacker could use this issue to cause NSS to crash, resulting in 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 libnss3 and / or libnss3-1d packages.
