Package        : kamailio
CVE ID         : CVE-2018-16657
Debian Bug     : 908324

Henning Westerholt discovered a flaw related to the Via header
processing in kamailio, a very fast, dynamic and configurable SIP
server. An unauthenticated attacker can take advantage of this flaw to
mount a denial of service attack via a specially crafted SIP message
with an invalid Via header.

For the stable distribution (stretch), this problem has been fixed in
version 4.4.4-2+deb9u3.

We recommend that you upgrade your kamailio packages.

For the detailed security status of kamailio please refer to its
security tracker page at:
https://security-tracker.debian.org/tracker/kamailio
