Jesse Ruderman and Bob Clary discovered memory safety issues affecting

page, an attacker could exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of the
user invoking Thunderbird. (CVE-2012-0442)
It was discovered that Thunderbird did not properly handle node removal in
the DOM. If the user were tricked into opening a specially crafted page, an
attacker could exploit this to cause a denial of service via application
crash, or potentially execute code with the privileges of the user invoking
Thunderbird. (CVE-2011-3659)
It was discovered that memory corruption could occur during the decoding of
Ogg Vorbis files. If the user were tricked into opening a specially crafted
file, an attacker could exploit this to cause a denial of service via
application crash, or potentially execute code with the privileges of the
user invoking Thunderbird. (CVE-2012-0444)
Nicolas Gregoire and Aki Helin discovered that when processing a malformed

through certain proxies might generate errors. An attacker might be able to
use this to read sensitive data from the error messages. (CVE-2011-3670)
