Description Mark J. Cox 2003-10-30 10:27:47 UTC

Herbert Xu discovered that a number of netlink applications do not
check the source address of incoming packets, assuming they are coming
from the kernel.  As any local user can send unicast netlink messages
to any process on the system, this can lead to a local denial of
service attack, or other local attacks.

quagga in RHEL3 is affected 

Currently embargoed.
