Description Mark J. Cox 2003-10-30 10:21:59 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.

Zebra in 2.1AS and 2.1AW is affected
Will add to RHSA-2003:305 errata in progress

Currently embargoed.
