Ubuntu 18.04 LTS / 20.04 LTS : NSS vulnerability (USN-5410-1)

high Nessus Plugin ID 161025

Language:

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-5410-1 advisory.

 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.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected libnss3, libnss3-dev and / or libnss3-tools packages.
