Mozilla Thunderbird is a standalone mail and newsgroup client.

Several flaws were found in the processing of malformed content. Malicious
content could cause Thunderbird to crash or, potentially, execute arbitrary
code with the privileges of the user running Thunderbird. (CVE-2012-1970,
CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975, CVE-2012-1976,
CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959, CVE-2012-3960,
CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)

Content containing a malicious Scalable Vector Graphics (SVG) image file
could cause Thunderbird to crash or, potentially, execute arbitrary code
with the privileges of the user running Thunderbird. (CVE-2012-3969,
CVE-2012-3970)

Two flaws were found in the way Thunderbird rendered certain images using
WebGL. Malicious content could cause Thunderbird to crash or, under certain
conditions, possibly execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2012-3967, CVE-2012-3968)

A flaw was found in the way Thunderbird decoded embedded bitmap images in
Icon Format (ICO) files. Content containing a malicious ICO file could
cause Thunderbird to crash or, under certain conditions, possibly execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2012-3966)

A flaw was found in the way the "eval" command was handled by the
Thunderbird Error Console. Running "eval" in the Error Console while
viewing malicious content could possibly cause Thunderbird to execute
arbitrary code with the privileges of the user running Thunderbird.
(CVE-2012-3980)

An out-of-bounds memory read flaw was found in the way Thunderbird used the
format-number feature of XSLT (Extensible Stylesheet Language
Transformations). Malicious content could possibly cause an information
leak, or cause Thunderbird to crash. (CVE-2012-3972)

A flaw was found in the location object implementation in Thunderbird.
Malicious content could use this flaw to possibly allow restricted content
to be loaded. (CVE-2012-3978)

Note: All issues except CVE-2012-3969 and CVE-2012-3970 cannot be exploited
by a specially-crafted HTML mail message as JavaScript is disabled by
default for mail messages. They could be exploited another way in
Thunderbird, for example, when viewing the full remote content of an RSS
feed.

All Thunderbird users should upgrade to this updated package, which
contains Thunderbird version 10.0.7 ESR, which corrects these issues. After
installing the update, Thunderbird must be restarted for the changes to
take effect.
