CVE-2018-7284 (GCVE-0-2018-7284)

Vulnerability from cvelistv5

Published

2018-02-22 00:00

Modified

2024-08-05 06:24

Severity ?

CWE

Summary

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.
