Description: A vulnerability was reported in Asterisk. A remote user can execute arbitrary code on the target system.
A remote user can send a specially crafted audit endpoint (AUEP) response message to trigger a stack overflow in the MGCP implementation
and execute arbitrary code on the target system.
Also, if an administrator uses a parameter that contains user-defined values
as a filename input to the Record() function, code execution may be possible.
The vendor was notified on August 10, 2006.
The
Mu Security research team discovered these vulnerabilities.
