Home / Security / Firefox 3.6 Exploit Could Be Causing Browser Crashes


Firefox is faced again with another challenge in the security of its latest browser, Firefox 3.6. As of late, I have noticed more browser crashes in the last two weeks in which could be a result of this exploit.Firefox 3.6 Exploit

There’s new zero day exploit in Firefox 3.6. The exploit allows attackers to remotely gain control of a PC. Russian security firm Intevydis develops the commercial VulnDisco add-on for the also commercial Canvas exploit toolkit by vendor Immunity. Intevydis made a Windows exploit for a previously unknown security hole in Firefox 3.6 available to its customers.

Mozilla (Firefox) hasn’t released any updates to correct this exploit, even though its been known since the beginning of February.

According to the analysis on the Extraexploit blog, a significant increase in the number of Firefox 3.6 crashes was noted on the 12th and 13th of February. It is unclear whether the crashes were connected to the exploit being tested. The pages causing the highest number of crashes are listed in Mozilla’s crash reports.

Mozilla needs to find a way to release updates a lot quicker to reduce the exposure of such exploits.

  1. yes that’s true! that there are sometimes that Firefox crashes. but anyway i love Firefox.

  2. I agree with your last sentence. I am a mozilla firefox browser user and I have definitely experienced these crashes. Really annoying especially if you’re right in the middle of doing something important. Mozilla should definitely find a solution to this and fast!

  3. I really enjoyed your article, I tweet!

  4. Yes firefox sometemes crashes. But it’s still the best because of add-ons.

  5. I’ve been using Firefox for a while, but about a year ago I switched to Google Chrome to try it out. Just recently then released a extensions feature which is basically the same thing as Add-Ons. I really prefer Chrome, and it’s a lot faster than the rest of web browsers. You guys should try it out sometime../

  6. I haven’t had too many of these crashes.

    It may be a little slower but the add ons are such a time saver and value adder it is totally worth whatever draw backs there are.

  7. Lovely. Just when I was getting to like Firefox (I changed only 3 months ago)…and now this.

    I guess I’ll keep my fingers crossed.

  8. That’s why I never rush to update to the latest and greatest. ;-) Thanks.
