Mozilla is advising fans of Firefox to update the stable version of the browser after it released a patch for a security bug marked “critical” today.
Available for Windows , Mac , and Linux , Firefox 3.6.12 patches a heap buffer overflow that could allow for remote code execution. Mozilla notes that the bug affects the current version 3.6 branch of Firefox, the legacy version 3.5 branch, and could potentially affect Thunderbird users who load Web pages in the RSS reader.
