Description Jan Lieskovsky 2010-08-24 08:58:37 EDT
A NULL pointer dereference flaw was found in the way Quagga's bgpd daemon
parsed paths of autonomous systems (AS). A configured BGP peer could send
a BGP update AS path request with unknown AS type, which could lead to
denial of service (bgpd daemon crash).

Not vulnerable. This issue did not affect the versions of quagga
package as shipped with Red Hat Enterprise Linux 3, 4, or 5, as
these versions do not support 4 byte AS numbers (AS4 support) yet.
