Synopsis

The remote Ubuntu host is missing a security update.

Description

Martin Thomson discovered that NSS incorrectly generated handshake hashes. A 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.
