Critical | Mozilla developers and community | Crashes with evidence of memory corruption (rv:1.8.0.12/1.8.1.4) |
Description
As part of the Firefox 2.0.0.4 and 1.5.0.12 update releases Mozilla developers fixed many bugs to improve the stability of the product. Some of these crashes that showed evidence of memory corruption under certain circumstances and we presume that with enough effort at least some of these could be exploited to run arbitrary code.
Thunderbird shares the browser engine with Firefox and could be vulnerable if JavaScript were to be enabled in mail. This is not the default setting and we strongly discourage users from running JavaScript in mail. Without further investigation we cannot rule out the possibility that for some of these an attacker might be able to prepare memory for exploitation through some means other than JavaScript, such as large images.
Workaround
Upgrade to the fixed versions. Do not enable JavaScript in Thunderbird or the mail portions of SeaMonkey.
