A vulnerability has been identified in Webmin and Usermin, which could be exploited by remote attackers to cause a denial of service or potentially execute arbitrary commands. This flaw is due to a format string error in "miniserv.pl" when logging failed authentication attempts via syslog, which could be exploited by remote unauthenticated attackers to crash and possibly compromise a vulnerable server by supplying a specially crafted username to the web administration interface (port 10000).
