thunderbird vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Multiple memory safety issues were discovered in Thunderbird. If the user
were tricked into opening a specially crafted message with scripting
enabled, an attacker could possibly exploit these to cause a denial of
service via application crash, or potentially execute code with the
privileges of the user invoking Thunderbird. (CVE-2013-0801,
CVE-2013-1669)

Cody Crews discovered that some constructors could be used to bypass
restrictions enforced by their Chrome Object Wrapper (COW). If a user had
scripting enabled, an attacker could exploit this to conduct cross-site
scripting (XSS) attacks. (CVE-2013-1670)

A use-after-free was discovered when resizing video content whilst it is
playing. If a user had scripting enabled, an attacker could potentially
exploit this to execute code with the privileges of the user invoking
Thunderbird. (CVE-2013-1674)

It was discovered that some DOMSVGZoomEvent functions could be used
without being properly initialized, which could lead to information
leakage. (CVE-2013-1675)

Abhishek Arya discovered multiple memory safety issues in Thunderbird. If
the user were tricked into opening a specially crafted message, an
attacker could possibly exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of
the user invoking Thunderbird. (CVE-2013-1676, CVE-2013-1677,
CVE-2013-1678, CVE-2013-1679, CVE-2013-1680, CVE-2013-1681)

Update instructions:

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

Ubuntu 13.04:
  thunderbird                     17.0.6+build1-0ubuntu0.13.04.1

Ubuntu 12.10:
  thunderbird                     17.0.6+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  thunderbird                     17.0.6+build1-0ubuntu0.12.04.1

After a standard system update you need to restart Thunderbird to make
all the necessary changes.
