# CVE-2018-7284: A Buffer Overflow issue was discovered… | CubePath

## 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.
