3. Description:
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-2012-0461,
CVE-2012-0462, CVE-2012-0464)
Two flaws were found in the way Thunderbird parsed certain Scalable Vector
Graphics (SVG) image files. An HTML mail message containing a malicious SVG
image file could cause an information leak, or cause Thunderbird to crash
or, potentially, execute arbitrary code with the privileges of the user
running Thunderbird. (CVE-2012-0456, CVE-2012-0457)
A flaw could allow malicious content to bypass intended restrictions,
possibly leading to a cross-site scripting (XSS) attack if a user were
tricked into dropping a "javascript:" link onto a frame. (CVE-2012-0455)
It was found that the home page could be set to a "javascript:" link. If a
user were tricked into setting such a home page by dragging a link to the
home button, it could cause Firefox to repeatedly crash, eventually leading
to arbitrary code execution with the privileges of the user running
Firefox. A similar flaw was found and fixed in Thunderbird. (CVE-2012-0458)
A flaw was found in the way Thunderbird parsed certain, remote content
containing "cssText". Malicious, remote content could cause Thunderbird to
crash or, potentially, execute arbitrary code with the privileges of the
user running Thunderbird. (CVE-2012-0459)
It was found that by using the DOM fullscreen API, untrusted content could
bypass the mozRequestFullscreen security protections. Malicious content
could exploit this API flaw to cause user interface spoofing.
(CVE-2012-0460)
A flaw was found in the way Thunderbird handled content with multiple
Content Security Policy (CSP) headers. This could lead to a cross-site
scripting attack if used in conjunction with a website that has a header
injection flaw. (CVE-2012-0451)
Note: All issues except CVE-2012-0456 and CVE-2012-0457 cannot be exploited
by a specially-crafted HTML mail message as JavaScript is disabled by
default for mail messages. It 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 10.0.3 ESR, which corrects these issues. After
installing the update, Thunderbird must be restarted for the changes to
take effect.
