Description Mark J. Cox 2005-08-11 05:27:25 EDT
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
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."

Patch and details:


We should fix this for RHEL4
Comment 3 James Morris 2005-08-11 12:12:26 EDT
SELinux does not grant capabilities to users.
Comment 4 Stephen Smalley 2005-11-15 05:54:26 EST
Correct - SELinux is presently restrictive only (i.e. only further restricts
access); use of a capability aka privilege still requires uid 0 (at least
initially) plus the corresponding SELinux permission.
