Mu Security research team has reported two vulnerabilities in Helix
DNA Server, which can be exploited by malicious people to cause a DoS
(Denial of Service) and potentially compromise a vulnerable system.

1) A boundary error within the RTSP service when handling the
"User-Agent" header can be exploited to cause a buffer overflow via a
specially crafted "User-Agent" header.

Successful exploitation may allow execution of arbitrary code.

2) An unspecified error exists within the parsing of HTTP URL
schemes.

The vulnerabilities have been reported in versions 10.0.x and 11.0.x.
