Description:
7
 
 A NULL pointer access issue was discovered in Asterisk 15.x through 15.2.1.
8
 
 The RTP support in Asterisk maintains its own registry of dynamic codecs
9
 
 and desired payload numbers. While an SDP negotiation may result in a codec
10
 
 using a different payload number, these desired ones are still stored
11
 
 internally. When an RTP packet was received, this registry would be
12
 
 consulted if the payload number was not found in the negotiated SDP. This
13
 
 registry was incorrectly consulted for all packets, even those which are
14
 
 dynamic. If the payload number resulted in a codec of a different type than
15
 
 the RTP stream (for example, the payload number resulted in a video codec
16
 
 but the stream carried audio), a crash could occur if no stream of that
17
 
 type had been negotiated. This was due to the code incorrectly assuming
18
 
 that a stream of that type would always exist.
