A Buffer Overflow issue exists in Asterisk up to and including 13.19.1, 14.x up to and including 14.7.5, and 15.x up to and including 15.2.1, and Certified Asterisk up to and including 13.18-cert2. When processing a SUBSCRIBE request, the res_pjsip_pubsub module stores the accepted formats present in the Accept headers of the request. This code did not limit the number of headers it processed, despite having a fixed limit of 32. If more than 32 Accept headers were present, the code would write outside of its memory and cause a crash.
