Debian Security Advisory DSA-1788-1 [email protected]

Package : quagga
Vulnerability : improper assertion
Problem type : remote
Debian-specific: no
Debian Bug : 526311
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.
