Ubuntu Several security issues were fixed in Thunderbird.
==========================================================================
Ubuntu Security Notice USN-2296-1
July 22, 2014

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

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

- Ubuntu 14.04 LTS
- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in Thunderbird.

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

Details:

Christian Holler, David Keeler and Byron Campen 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-2014-1547)

Atte Kettunen discovered a buffer overflow when interacting with WebAudio
buffers. 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-2014-1549)

Atte Kettunen discovered a use-after-free in WebAudio. 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-2014-1550)

Jethro Beekman discovered a use-after-free when the FireOnStateChange
event is triggered 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 priviliges of
the user invoking Thunderbird. (CVE-2014-1555)

Patrick Cozzi discovered a crash when using the Cesium JS library to
generate WebGL content. If a user had enabled scripting, an attacker could
potentially exploit this to execute arbitrary code with the privilges of
the user invoking Thunderbird. (CVE-2014-1556)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free in
CERT_DestroyCertificate. 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-2014-1544)

A crash was discovered in Skia when scaling an image, if the scaling
operation takes too long. 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-2014-1557)

Christian Holler discovered several issues when parsing certificates
with non-standard character encoding, resulting in the inability to
use valid SSL certificates in some circumstances. (CVE-2014-1558,
CVE-2014-1559, CVE-2014-1560)

Boris Zbarsky discovered that network redirects could cause an iframe
to escape the confinements defined by its sandbox attribute in some
circumstances. If a user had enabled scripting, an attacker could
potentially exploit this to conduct cross-site scripting attacks.
(CVE-2014-1552)

Update instructions:

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

Ubuntu 14.04 LTS:
  thunderbird                     1:31.0+build1-0ubuntu0.14.04.1

Ubuntu 12.04 LTS:
  thunderbird                     1:31.0+build1-0ubuntu0.12.04.1

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