Ubuntu Security Notice (C) 2005-2013 Canonical, Inc. / NASL script (C) 2006-2013 Tenable Network Security, Inc.
The remote Ubuntu host is missing one or more security-related patches.
A buffer overflow was discovered in the XBM image handler. By tricking
an user into opening a specially crafted XBM image, an attacker could
exploit this to execute arbitrary code with the user's privileges.
Mats Palmgren discovered a buffer overflow in the Unicode string
parser. Unicode strings that contained 'zero-width non-joiner'
characters caused a browser crash, which could possibly even exploited
to execute arbitrary code with the user's privileges. (CAN-2005-2702)
This could be exploited to run arbitrary code under some conditions.
Peter Zelezny discovered that URLs which are passed to Thunderbird on
the command line are not correctly protected against interpretation by
the shell. If Thunderbird is configured as the default handler for
'mailto:' URLs, this could be exploited to execute arbitrary code with
user privileges by tricking the user into clicking on a specially
crafted URL (for example, in an email or chat client). (CAN-2005-2968)
This update also fixes some less critical issues which are described
(CAN-2005-2703, CAN-2005-2704, CAN-2005-2706, CAN-2005-2707)
The 'enigmail' plugin has been updated to work with the new
Thunderbird and Mozilla versions.
Update the affected packages.
