http://secunia.com/advisories/26431/

CRITICAL:
Less critical

IMPACT:
Exposure of system information, DoS

WHERE:
>From local network

SOFTWARE:
Diskeeper 9.x
http://secunia.com/product/5514/

DESCRIPTION:
Pravus has discovered two vulnerabilities in Diskeeper, which can be
exploited by malicious people to cause a DoS (Denial of Service) or
disclose certain system information.

The vulnerabilities are caused due to input validation errors within
the Diskeeper service (DkService.exe) when handling arguments passed
to RPC requests with opcode 0x01. These can be exploited to crash the
service or gain knowledge of certain system information (e.g. Windows
version, address of loaded modules) via a specially crafted RPC
request sent to default port 31038/TCP.

The vulnerabilities are confirmed in Diskeeper 2007 - ProPremier and
reportedly affects Diskeeper 9 Professional. Other versions may also
be affected.

SOLUTION:
Restrict access to the service.

PROVIDED AND/OR DISCOVERED BY:
Pravus
