While surfing through one of my favorite blogs ghacks, i came across the news of serious security vulnerability in firefox 3.5.
This serious vulnerability is discovered by Simon Berry and is posted on the milw0rm security portel under the title ” Firefox 3.5 Heap Spray Vulnerabilty”. This news is allready confirmed by mozillalinks and they have allready published the security patch for this.
This vulnerability could be fixed by following these simple steps:
- Enter about:config in the location bar to access advanced preferences.
- Look for javascript.options.jit.content and double click it to set it to false.
Since, the vulnerability is related to TraceMonkey JavaScript optimizer, users needs to mitigate it by temporarily disabling the optimizer. By this the javascript performance of firefox3.5 would be reduced but we trust that the mozilla team will prepare a quick official patch for solving the problem.
