TITLE:
Doomsday Format String Vulnerabilities
SECUNIA ADVISORY ID:
SA19515
VERIFY ADVISORY:
http://secunia.com/advisories/19515/
CRITICAL:
Highly critical
IMPACT:
DoS, System access
WHERE:
From remote
SOFTWARE:
Doomsday 1.x
http://secunia.com/product/9154/
DESCRIPTION:
Luigi Auriemma has reported two vulnerabilities in Doomsday, which
can be exploited by malicious people to cause a DoS (Denial of
Service) and potentially compromise a vulnerable system.
The vulnerabilities are caused due to format string errors in the
"Con_Message()" and "conPrintf()" functions and can be exploited by
connecting to port 13209/tcp and passing a specially crafted JOIN
command containing format specifiers.
Successful exploitation crashes the server and may potentially allow
code execution.
The vulnerabilities have been reported in version 1.8.6 and current
SVN version 1.9.0. Other versions may also be affected.
SOLUTION:
Host and play games on trusted networks only.
Use another product.
