USN-5410-1: NSS vulnerability

11 May 2022

NSS could be made to stop responding if it received a specially crafted message.

Releases

Packages

  • nss - Network Security Service library

Details

Lenny Wang discovered that NSS incorrectly handled certain
messages. A remote attacker could possibly use this issue to cause
servers compiled with NSS to stop responding, resulting in a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.04
Ubuntu 18.04

After a standard system update you need to restart any applications that
use NSS to make all the necessary changes.
