Cisco Meeting Server Session Description Protocol Media Lines Buffer Overflow Vulnerability

A vulnerability in the Session Description Protocol (SDP) parser of Cisco Meeting Server could allow an unauthenticated, remote attacker to execute arbitrary code on an affected system.

The vulnerability exists because the affected software performs incomplete input validation of the size of media lines in session descriptions. An attacker could exploit this vulnerability by sending crafted packets to the SDP parser on an affected system. A successful exploit could allow the attacker to cause a buffer overflow condition on an affected system, which could allow the attacker to execute arbitrary code on the system.

Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
