November 04, 2015
nss vulnerabilities
==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
– Ubuntu 15.10
– Ubuntu 15.04
– Ubuntu 14.04 LTS
– Ubuntu 12.04 LTS
Summary:
NSS could be made to crash or run programs if it received specially
crafted input.
Software Description:
– nss: Network Security Service library
Details:
Tyson Smith and David Keeler discovered that NSS incorrectly handled
decoding certain ASN.1 data. An remote attacker could use this issue to
cause NSS to crash, resulting in a denial of service, or possibly execute
arbitrary code.
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 15.10:
libnss3 2:3.19.2.1-0ubuntu0.15.10.1
Ubuntu 15.04:
libnss3 2:3.19.2.1-0ubuntu0.15.04.1
Ubuntu 14.04 LTS:
libnss3 2:3.19.2.1-0ubuntu0.14.04.1
Ubuntu 12.04 LTS:
libnss3 3.19.2.1-0ubuntu0.12.04.1
After a standard system update you need to restart any applications that
use NSS, such as Evolution and Chromium, to make all the necessary changes.
