CVE-2017-16671  (opens in a new tab)
CWE-119  (opens in a new tab)

How to fix?

Upgrade asterisk to version 13.18.1, 14.7.1, 15.1.1 or higher.

Overview

Affected versions of this package are vulnerable to Out-of-Bounds. 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.
