Mozilla this week released an incremental update to Firefox -- version 3.5.6 -- which fixes a handful of security threats ranging from low to near critical, as well as several stability issues, the company said.
Sitting higher up the security totem pole, the latest update addresses crashes with evidence of memory corruption, memory safety fixes in liboggplay media library, and an integer overflow issue. It also fixes an NTLM reflection vulnerability, location bar spooking vulnerability, and privilege escalation via chrome window opener, all of which were either classified as 'high' or 'moderate.'
Firefox should have already downloaded and installed the update. If not, you can update manually by clicking Help>Check for Updates.
