A vulnerability has been identified in Mozilla Firefox and Mozilla Suite, which could be exploited by remote attackers to execute arbitrary commands. This flaw is due to a buffer overflow error in the "NormalizeIDN" function when handling malformed URLs containing "soft hyphen" characters (0xAD) embedded in an HTML tag (e.g. "A HREF"), which could be exploited by remote attackers to take complete control of an affected system via specially crafted Web pages.
