[***** Start Mozilla Foundation Security Advisory 2007-29 *****] Known Vulnerabilities in Mozilla Products (Firefox 2.0.0.8) > MFSA 2007-29 Mozilla Foundation Security Advisory 2007-29 Title: Crashes with evidence of memory corruption (rv:1.8.1.8) Impact: Critical Announced: October 18, 2007 Reporter: Mozilla developers and community Products: Firefox, Thunderbird, SeaMonkey Fixed in: Firefox 2.0.0.8 Thunderbird 2.0.0.8 SeaMonkey 1.1.5 Description As part of the Firefox 2.0.0.8 update releases Mozilla developers fixed many bugs to improve the stability of the product. Some of these crashes 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 Disable JavaScript until a version containing these fixes can be installed. References L. David Baron, Boris Zbarsky, Georgi Guninski, Paul Nickerson, Olli Pettay, Jesse Ruderman, Vladimir Sukhoy, Daniel Veditz, and Martijn Wargers reported crashes in the browser engine. CVE-2007-5339 Browser crashes Igor Bukanov, Eli Friedman, and Jesse Ruderman reported crashes in the JavaScript engine.
