Paul Jakma discovered that specially crafted UPDATE messages can
trigger an out of boundary read that can result in a system crash of
quagga, the BGP/OSPF/RIP routing daemon.

For the old stable distribution (sarge) this problem has been fixed in
version 0.98.3-7.4.

For the stable distribution (etch) this problem has been fixed in
version 0.99.5-5etch2.

For the unstable distribution (sid) this problem has been fixed in
version 0.99.6-5.

We recommend that you upgrade your quagga package.
