It was discovered that the bgpd daemon in the Quagga routing suite does not properly calculate the length of multi-segment AS_PATH UPDATE messages, causing bgpd to drop a session and potentially resulting in loss of network connectivity. For the oldstable distribution (jessie), this problem has been fixed in version 0.99.23.1-1+deb8u4. For the stable distribution (stretch), this problem has been fixed in version 1.1.1-3+deb9u1. We recommend that you upgrade your quagga packages.
