| Beschreibung: | Summary:
Mozilla Firefox is prone to multiple vulnerabilities.
Vulnerability Insight:
Multiple flaws are due to following errors:
- An array indexing error exists when allocating space for floating point
numbers. This can be exploited to trigger a memory corruption when a
specially crafted floating point number is processed.
- 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.
- When parsing regular expressions used in Proxy Auto-configuration. This can
be exploited to cause a crash or potentially execute arbitrary code via
specially crafted configured PAC files.
- 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.
- An error in the 'XPCVariant::VariantDataToJS()' XPCOM utility, which can be
exploited to execute arbitrary JavaScript code with chrome privileges.
- An error in the implementation of the JavaScript 'document.getSelection()'
can be exploited to read text selected on a web page in a different domain.
- 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.

bypass certain security restrictions, manipulate certain data, or compromise
a user's system.
