This can be exploited to trigger a memory corruption when a specially crafted floating point number is processed. Successful exploitation allows execution of arbitrary code. The vulnerability is confirmed in version 3.0.14 and 3.5.3. Prior versions may also be affected. 2) An error in the form history functionality can be exploited to disclose history entries via a specially crafted web page that triggers the automatic filling of form fields. 3) An error when creating JavaScript web-workers recursively can be exploited to trigger the use of freed memory and cause a crash or potentially execute arbitrary code. 4) An error exists when parsing regular expressions used in Proxy Auto-configuration (PAC). This can be exploited to cause a crash or potentially execute arbitrary code via specially crafted configured PAC files. 5) An error when processing GIF color maps can be exploited to cause a heap-based buffer overflow and potentially execute arbitrary code via a specially crafted GIF file. 6) An error in the "XPCVariant::VariantDataToJS()" XPCOM utility can be exploited to execute arbitrary JavaScript code with chrome privileges. 7) An error in the implementation of the JavaScript "document.getSelection()" function can be exploited to read text selected on a web page in a different domain. 8) An error when downloading files can be exploited to display different file names in the download dialog title bar and download dialog body. This can be exploited to obfuscate file names via a right-to-left override character and potentially trick a user into running an executable file. 9) An error in the embedded liboggz library can be exploited to cause a crash or potentially execute arbitrary code. 10) Multiple errors in the embedded libvorbis library can be exploited to cause crashes or potentially execute arbitrary code. 11) An error in the embedded liboggplay library can be exploited to cause a crash or potentially execute arbitrary code. 12) Multiple errors in the Firefox 3 and Firefox 3.5 browser engines can be exploited to cause crashes or potentially execute arbitrary code. 13) Multiple errors in the Firefox 3.5 browser engine can be exploited to cause crashes or potentially execute arbitrary code. 14) An error in the Firefox 3 browser engine can be exploited to cause a crash or potentially execute arbitrary code. 15) Multiple errors in the Firefox 3.5 JavaScript engine can be exploited to cause crashes or potentially execute arbitrary code. SOLUTION: Update to version 3.0.15 or 3.5.4.
