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.

chan_sip.c in the SIP channel driver in Asterisk Open Source 1.6.x before 1.6.2.18.1 and 1.8.x before 1.8.4.3 does not properly handle '\0' characters in SIP packets, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via a crafted packet.
