Description Jan Lieskovsky 2010-11-18 12:09:22 UTC
A security flaw was found in the way Quagga bgpd daemon
processed certain route metrics information. A configured BGP peer
could use this flaw to send a BGP message with specially-crafted
value of AS-path attribute, which would cause the bgpd daemon on
all systems on the route the message travels to reset the BGP session.

Comment 9 Jan Lieskovsky 2011-03-22 16:10:48 UTC
This issue did NOT affect the versions of the quagga package,
as shipped with Red Hat Enterprise Linux 4 and 5, as they
did not include support for AS-Pathlimit feature yet.


This issue affects the version of the quagga package, as shipped
with Red Hat Enterprise Linux 6.


This issue affects the versions of the quagga package, as shipped
with Fedora release of 13 and 14.
