Ubuntu 12.04 LTS / 14.04 LTS / 15.10 / 16.04 LTS : nss vulnerability (USN-3029-1)
High Nessus Plugin ID 92010
SynopsisThe remote Ubuntu host is missing a security-related patch.
DescriptionTyson Smith and Jed Davis discovered that NSS incorrectly handled memory. A remote attacker could use this issue to cause NSS to crash, resulting in a denial of service, or possibly execute arbitrary code.
This update refreshes the NSS package to version 3.23 which includes the latest CA certificate bundle. As a security improvement, this update also modifies NSS behaviour to reject DH key sizes below 1024 bits, preventing a possible downgrade attack.
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.
SolutionUpdate the affected libnss3 package.
