CVE-2018-7285 [HIGH] CWE-476 CVE-2018-7285: A NULL pointer access issue was discovered in Asterisk 15.x through 15.2.1. The RTP support in Aster A NULL pointer access issue was discovered in Asterisk 15.x through 15.2.1. The RTP support in Asterisk maintains its own registry of dynamic codecs and desired payload numbers. While an SDP negotiation may result in a codec using a different payload number, these desired ones are still stored internally. When an RTP packet was received, this registry w
