Mozilla FireFox 3.5.3 Final

What’s New in Firefox 3.5.3

Firefox 3.5.3 fixes the following issues:

Several security issues

Impact key:

• Critical: Vulnerability can be used to run attacker code and install software, requiring no user interaction beyond normal browsing.
• High: Vulnerability can be used to gather sensitive data from sites in other windows or inject data or code into those sites, requiring no more than normal browsing actions.
• Moderate: Vulnerabilities that would otherwise be High or Critical except they only work in uncommon non-default configurations or require the user to perform complicated and/or unlikely steps.
• Low: Minor security vulnerabilities such as Denial of Service attacks, minor data leaks, or spoofs. (Undetectable spoofs of SSL indicia would have "High" impact because those are generally used to steal sensitive data intended for other sites.

Fixed several stability issues:

• MFSA 2009-51 Chrome privilege escalation with FeedWriter

• MFSA 2009-50 Location bar spoofing via tall line-height Unicode characters

• MFSA 2009-49 TreeColumns dangling pointer vulnerability

• MFSA 2009-47 Crashes with evidence of memory corruption (rv:1.9.1.3/1.9.0.14)
