Ubuntu 12.04 LTS : nss vulnerability (USN-1540-2)

Ubuntu Security Notice (C) 2012-2016 Canonical, Inc. / NASL script (C) 2012-2016 Tenable Network Security, Inc.


Synopsis :

The remote Ubuntu host is missing a security-related patch.

Description :

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

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.

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.

Solution :

Update the affected libnss3 package.

Risk factor :

Medium / CVSS Base Score : 5.0
(CVSS2#AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVSS Temporal Score : 3.7
