{"vuid":"VU#755513","idnumber":"755513","name":"Mozilla products vulnerable to memory corruption in the JavaScript engine","keywords":["Mozilla","Firefox","DoS","denial of service","arbitrary code execution","arbitrary command execution","memory corruption","JavaScript","mail","mozilla_101907"],"overview":"A number of vulnerabilities in the Mozilla JavaScript engine may allow the execution of arbitrary code or denial of service.","clean_desc":"The Mozilla JavaScript engine contains several vulnerabilities that may result in memory corruption. The impact of this memory corruption in specific cases is unclear. According to Mozilla Foundation Security Advisory MFSA 2007-29: 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. Information about the individual flaws causing the vulnerabilities addressed in this update can be found in the references section of this document. Note that the Thunderbird email client also uses the Mozilla JavaScript engine and could be affected by these vulnerabilities if JavaScript is enabled (it is disabled by default).","impact":"Potential impacts of these vulnerabilities include remote execution of arbitrary code and denial of service.","resolution":"Upgrade\nThese vulnerabilities are addressed in Firefox 2.0.0.8, Thunderbird 2.0.0.8, and SeaMonkey 1.1.5. Users that are unable to update should consider the following workaround:","workarounds":"Disable JavaScript For instructions on how to disable JavaScript in Firefox, please refer to the Firefox section of the Securing Your Web Browser document.","sysaffected":"","thanks":"Thanks to Mozilla for reporting this vulnerability.
