4Subject: [PATCH] gstrtspconnection: Security loophole making heap overflow
5
6The former code allowed an attacker to create a heap overflow by
7sending a longer than allowed session id in a response and including a
8semicolon to change the maximum length. With this change, the parser
9will never go beyond 512 bytes.
