TITLE:
Helix Server Two Denial of Service Vulnerabilities

SECUNIA ADVISORY ID:
SA35815

VERIFY ADVISORY:
http://secunia.com/advisories/35815/

DESCRIPTION:
Core Security has reported two vulnerabilities in Helix Server, which
can be exploited by malicious people to cause a DoS (Denial of
Service).

1) A NULL pointer dereference error in the RTSP (SET_PARAMETERS)
request handling when receiving a request with an empty
DataConvertBuffer parameter can be exploited to cause the service to
become unresponsive or crash.

2) An error in the SETUP request handling can be exploited to crash
the process via a specially crafted request not containing a 0x2F
byte in the request line.

The vulnerabilities are reported in version 12.0.1.215 (Tahiti) Build
175002/12667. Other versions may also be affected.

SOLUTION:
Upgrade to version 13.0.0, which fixes the vulnerabilities.
