Michal Zalewski has discovered a weakness in Firefox, which can be exploited by malicious people to cause a DoS (Denial of Service).
The weakness is caused due to an unspecified error and can be exploited to corrupt memory.
Successful exploitation crashes the browser. Execution of arbitrary code has not been proven, but can't be completely ruled out.
The weakness has been confirmed in version 184.108.40.206 for Windows. Other versions may also be affected.
NOTE: Secunia normally doesn't classify a browser crash as a vulnerability nor issue an advisory about it. However, the potential risc of this issue may be more severe than currently believed, which justifies for an advisory being issued.
