Summary

Daniel McCarney discovered that the BIRD internet routing daemon
incorrectly validated RFC 8203 messages in it's BGP daemon, resulting
in a stack buffer overflow.

For the stable distribution (buster), this problem has been fixed in
version 1.6.6-1+deb10u1. In addition this update fixes an incomplete
revocation of privileges and a crash triggerable via the CLI (the latter
two bugs are also fixed in the oldstable distribution (stretch) which is
not affected by CVE-2019-16159).

We recommend that you upgrade your bird packages.
