Security database references:
In Mitre's CVE dictionary: CVE-2019-16159.
More information:

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.
