Firefox 3.6.12 fixes a critical security issue

After the release of Firefox 3.6.11 Mozilla has presented the next version of the successful web browser. More or less pleasant, of course, are the reasons that led to a new update. Morten Kråkvik has found a vulnerability in Firefox, with that he could provoke a heap buffer overflow. This makes it theoretically possible that an attacker could execute malicious code on the computer.

The vulnerability can be achieved by the use of Javascript functions document.write exploit with DOM. This problem affect the versions Firefox 3.6 and 5.3, also Thunderbird and SeaMonkey are affected. It is gratifying, however, that Mozilla has reacted quickly and has now fixed the vulnerability. With the new version Firefox 3.6.12, surfing through the internet is safe again.
