Debian DSA-4528-1 : bird - security update

high Nessus Plugin ID 129074

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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

Solution

Upgrade the bird packages.

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 ).
