Mozilla Patch Plugs a Safari Hole

Mozilla has patched a pair of critical vulnerabilities in Firefox, taking the unusual step of updating the older version 2.0 on Tuesday but delaying the fixes for the newer version 3.0 until Wednesday. Both updates, labeled Firefox 2.0.0.16 and Firefox 3.0.1, plug two holes rated critical by Mozilla, which uses a four-step threat ranking system. One of the flaws patched in 2.0.0.16 and 3.0.1 was credited to security researcher Billy Rios, who wrote last month about a blended threat to Windows users who had both Apple’s Safari browser and Firefox installed on the same system
