Description
A Buffer Overflow issue was discovered in Asterisk through 13.19.1, 14.x through 14.7.5, and 15.x through 15.2.1, and Certified Asterisk through 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.
Affected configurations
• digium asterisk (<= 13.19.1)
• digium asterisk (>= 14.0.0 <= 14.7.5)
• digium asterisk (>= 15.0.0 <= 15.2.1)
• digium certified asterisk 13.18
• digium certified asterisk (<= 13.18)
• debian debian linux 9.0
