Mozilla Firefox/Thunderbird/SeaMonkey Multiple HTML Injection Vulnerabilities
Mozilla Firefox 3.5.11 - 3.6.10, Mozilla SeaMonkey 2.0 - 2.0.9
Vulnerable Platforms Details
Mozilla Firefox/Thunderbird/SeaMonkey Multiple HTML Injection Vulnerabilities. Mozilla Firefox, SeaMonkey, and Thunderbird are prone to multiple HTML-injection vulnerabilities. Successful exploits will allow attacker-supplied HTML and script code to run in the context of the affected browser, potentially allowing the attacker to steal cookie-based authentication credentials or to control how the site is rendered to the user. Other attacks are also possible.
Multiple cross-site scripting (XSS) vulnerabilities in the rendering engine in Mozilla Firefox before 3.5.16 and 3.6.x before 3.6.13, and SeaMonkey before 2.0.11, allow remote attackers to inject arbitrary web script or HTML via (1) x-mac-arabic, (2) x-mac-farsi, or (3) x-mac-hebrew characters.
This issue is fixed in Firefox 3.6.13, Firefox 3.5.16, SeaMonkey 2.0.11. Mozilla Products - Download Reference
