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

- Ubuntu 13.10
- 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:

Benoit Jacob, Olli Pettay, Jan Varga, Jan de Mooij, Jesse Ruderman, Dan
Gohman and Christoph Diehl discovered multiple memory safety issues in
Thunderbird. If a user were tricked in to opening a specially crafted
message with scripting enabled, an attacker could potentially exploit
these to cause a denial of service via application crash, or execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2014-1493)

Atte Kettunen discovered an out-of-bounds read during WAV file decoding.
If a user had enabled audio, an attacker could potentially exploit this
to cause a denial of service via application crash. (CVE-2014-1497)

Robert O'Callahan discovered a mechanism for timing attacks involving
SVG filters and displacements input to feDisplacementMap. If a user had
enabled scripting, an attacker could potentially exploit this to steal
confidential information across domains. (CVE-2014-1505)

Tyson Smith and Jesse Schwartzentruber discovered an out-of-bounds read
during polygon rendering in MathML. If a user had enabled scripting, an
attacker could potentially exploit this to steal confidential information
across domains. (CVE-2014-1508)

John Thomson discovered a memory corruption bug in the Cairo graphics
library. If a user had a malicious extension installed, an attacker could
potentially exploit this to cause a denial of service via application
crash, or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2014-1509)

Mariusz Mlynski discovered that web content could open a chrome privileged
page and bypass the popup blocker in some circumstances. If a user had
enabled scripting, an attacker could potentially exploit this to execute
arbitrary code with the privileges of the user invoking Thunderbird.
(CVE-2014-1510, CVE-2014-1511)

It was discovered that memory pressure during garbage collection resulted
in memory corruption in some circumstances. If a user had enabled
scripting, an attacker could potentially exploit this to cause a denial
of service via application crash or execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2014-1512)

Jüri Aedla discovered out-of-bounds reads and writes with TypedArrayObject
in some circumstances. If a user had enabled scripting, an attacker could
potentially exploit this to cause a denial of service via application
crash or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2014-1513)

George Hotz discovered an out-of-bounds write with TypedArrayObject. If a
user had enabled scripting, an attacker could potentially exploit this to
cause a denial of service via application crash or execute arbitrary code
with the privileges of the user invoking Thunderbird. (CVE-2014-1514)

Update instructions:

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

Ubuntu 13.10:
  thunderbird                     1:24.4.0+build1-0ubuntu0.13.10.2

Ubuntu 12.10:
  thunderbird                     1:24.4.0+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
  thunderbird                     1:24.4.0+build1-0ubuntu0.12.04.1

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