Debian: DSA-1787-1: New quagga packages fix denial of service
Summary
It was discovered that Quagga, an IP routing daemon, could no longer
process the Internet routing table due to broken handling of multiple
4-byte AS numbers in an AS path. If such a prefix is received, the
BGP daemon crashes with an assert failure, leading to a denial of
service.
The old stable distribution (etch) is not affected by this issue.
For the stable distribution (lenny), this problem has been fixed in
version 0.99.10-1lenny2.
For the unstable distribution (sid), this problem has been fixed in
version 0.99.11-2.
We recommend that you upgrade your quagga package.
