4) Description of Vulnerability

Secunia Research has discovered two vulnerabilities in the Provideo
GMAXPlayer ActiveX Control, which can be exploited by malicious people
to compromise a user's system.

1) A boundary error in AXPlayer.ocx when receiving network responses
from a device connection specified via the "URL" and "CtrlPort"
object parameters can be exploited to cause a stack-based buffer
overflow.

2) A boundary error in AXPlayer.ocx when processing the "UserName"
and "Password" object parameters can be exploited to cause a
heap-based buffer overflow.

Successful exploitation of the vulnerabilities allows execution of
arbitrary code.
