Description Mark J. Cox 2005-08-11 09:28:22 UTC 
Some ipvs overflows were found and fixed in 2.4 (20050531) and later forward
ported to 2.6 (20050626)

"The impact of the bugs is a kernel stack overflow and privilege escalation
from CAP_NET_ADMIN via the IP_VS_SO_SET_STARTDAEMON/IP_VS_SO_GET_DAEMON
ioctls.  People running with 'root=all caps' (i.e., most users) are not
really affected (there's nothing to escalate), but SELinux and similar
users should take it seriously if they grant CAP_NET_ADMIN to other users."

We should fix this for RHEL4
