nss vulnerability
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 20.04 LTS
- Ubuntu 18.04 LTS
Summary:
NSS could be made to stop responding if it received a specially crafted
message.
Software Description:
- 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 LTS:
libnss3 2:3.49.1-1ubuntu1.7
Ubuntu 18.04 LTS:

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