  • nss - Network Security Service library

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 11.10
Ubuntu 11.04
Ubuntu 10.04

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