Ubuntu 14.04 LTS / 16.04 LTS / 16.10 / 17.04 : nss vulnerability (USN-3336-1)

Medium Nessus Plugin ID 100988

Synopsis

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

Description

It was discovered that NSS incorrectly handled certain empty SSLv2 messages. A remote attacker could possibly use this issue to cause NSS to crash, resulting in a denial of service.

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.

Solution

Update the affected libnss3 package.
