Mandriva Linux Security Advisory 2014-078
Posted Apr 16, 2014

Mandriva Linux Security Advisory 2014-078 - Sending a HTTP request that is handled by Asterisk with a large number of Cookie headers could overflow the stack. You could even exhaust memory if you sent an unlimited number of headers in the request. An attacker can use all available file descriptors using SIP INVITE requests. Asterisk will respond with code 400, 420, or 422 for INVITEs meeting this criteria. Each INVITE meeting these conditions will leak a channel and several file descriptors. The file descriptors cannot be released without restarting Asterisk which may allow intrusion detection systems to be bypassed by sending the requests slowly. The updated packages has been upgraded to the 11.8.1 version which is not vulnerable to these issues.
