With Firefox 220.127.116.11, Mozilla fixes at least 12 documented vulnerabilities -- five rated critical -- that could put users at risk of arbitrary file upload, arbitrary code execution, URL spoofing and cross-site scripting attacks.
The update is available for Windows, Mac OS X and Linux users.
Mozilla is recommending that all users upgrade to the shiny new Firefox 3 but, because of compatibility issues with add-ons and extensions, some users are hesitant to upgrade immediately.
The Firefox 2 patch is being distributed via the browser's automatic updates mechanism but there's a small worry that some users who install but never use the browser will still be at risk.
The newest Firefox 3 is known to be vulnerable to a highly critical vulnerability that is not yet patched.
Details on the Firefox 2 patches:
- MFSA 2008-33 Crash and remote code execution in block reflow
- MFSA 2008-32 Remote site run as local file via Windows URL shortcut
