Software Description:

Details:

Jan de Mooij, Christian Holler, Karl Tomlinson, Randell Jesup, Gary Kwong,
Jesse Ruderman and JW Wang 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-2014-1553, CVE-2014-1562)

Abhishek Arya discovered a use-after-free during DOM interactions with
SVG. If a user were tricked in to opening a specially crafted message
with scripting enabled, 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-2014-1563)

Michal Zalewski discovered that memory is not initialized properly during
GIF rendering in some circumstances. If a user were tricked in to opening
a specially crafted message, an attacker could potentially exploit this to
steal confidential information. (CVE-2014-1564)

Holger Fuhrmannek discovered an out-of-bounds read in Web Audio. If a
user were tricked in to opening a specially crafted message with scripting
enabled, an attacker could potentially exploit this to cause a denial of
service via application crash or steal confidential information.
(CVE-2014-1565)

A use-after-free was discovered during text layout in some circumstances.
If a user were tricked in to opening a specially crafted message with
scripting enabled, 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-2014-1567)

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

Ubuntu 12.04 LTS:
  thunderbird                     1:31.1.1+build1-0ubuntu0.12.04.1
