Ubuntu 12.04 LTS / 14.04 LTS / 15.10 : nss vulnerability (USN-2924-1)

Medium Nessus Plugin ID 89827


The remote Ubuntu host is missing a security-related patch.


Francis Gabriel discovered that NSS incorrectly handled decoding certain ASN.1 data. An remote 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 package.
