CVE-2017-16671 (opens in a new tab)How to fix?
Upgrade Debian:11 asterisk to version 1:13.18.1~dfsg-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream asterisk package and not the asterisk package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
A Buffer Overflow issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before 13.13-cert7. No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. NOTE: this is different from CVE-2017-7617, which was only about the Party A buffer.
