Details

USN-1540-1 fixed vulnerabilities in NSS. This update provides the
corresponding updates for Ubuntu 12.04 LTS.

Original advisory details:

Kaspar Brand discovered a vulnerability in how the Network Security
Services (NSS) ASN.1 decoder handles zero length items. If the user were
tricked into opening a specially crafted certificate, an attacker could
possibly exploit this to cause a denial of service via application crash.

Update instructions

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

Ubuntu 12.04

• libnss3 - 3.13.1.with.ckbi.1.88-1ubuntu6.1

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