Firefox JavaScript security problem!

By Derek Sooman

On April 5, 2005, 11:49 AM

Proving that IE is not the only browser that can get bad press for security glitches, it has emerged that Firefox has a vulnerability that could be exploited by malicious people to gain knowledge of potentially sensitive information. This security glitch is caused by an error in the JavaScript engine, as "a 'lambda' replace exposes arbitrary amounts of heap memory after the end of a JavaScript string."

Users concerned about this issue are advised to immediately turn off JavaScript support. Secunia has provided an online test to allow Firefox and Mozilla users to determine if they are affected by the bug.
