TITLE:
Apple Darwin Streaming Server Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA25193

VERIFY ADVISORY:
http://secunia.com/advisories/25193/

CRITICAL:
Highly critical

IMPACT:
DoS, System access

WHERE:
>From remote

SOFTWARE:
Darwin Streaming Server 4.x
http://secunia.com/product/1146/
Darwin Streaming Server 5.x
http://secunia.com/product/3085/

DESCRIPTION:
Two vulnerabilities have been reported in Apple Darwin Streaming
Server, which can be exploited by malicious people to cause a DoS
(Denial of Service) or to compromise a vulnerable system.

1) A boundary error in Darwin Streaming Proxy within the "is_command"
function can be exploited to cause a stack-based buffer overflow via a
specially crafted RTSP request.

2) A boundary error in Darwin Streaming Proxy while processing
"trackID" values within a "SETUP" request can be exploited to cause a
heap-based buffer overflow via a specially crafted RTSP request
containing more than 32 values.

Successful exploitation allows arbitrary code execution or a DoS.

The vulnerabilities are reported in Darwin Streaming Proxy 5.5.4 and
4.1. Other versions may also be affected.

NOTE: The Darwin Streaming Proxy 4.1 binary release for Fedora Core
is reportedly not vulnerable.

SOLUTION:
Update to version 5.5.5.
