The vulnerability is caused due to an error in the handling of an URL that contains the 0xAD character in its domain name. This can be exploited to cause a heap-based buffer overflow. Successful exploitation crashes Firefox and may potentially allow code execution but requires that the user is tricked into visiting a malicious web site or open a specially crafted HTML file. The vulnerability has been confirmed in version 1.0.6, and is reported to affect versions prior to 1.0.6, and version 1.5 Beta 1. SOLUTION: Don't browse untrusted web sites.
