Description Mark J. Cox 2004-06-25 04:55:07 EDT

An audit by SUSE found a missing "must be owner of the file" check in
inode_change_ok().  In the 2.6 kernel this allows a local user to be
able to change the groupid of any object (except those setgid) by
using chown.  In the 2.4 kernel this is exploitable only via a kernel
nfsd export where the server will grant requests to change GID when it
shouldn't.

SUSE suggested an embargo date of Jul14 1600MEST but this has been
adjusted to Jun29 1600MEST.

Comment 1 Mark J. Cox 2004-07-02 03:05:52 EDT

Embargo moved to Jul02 1000MEST

Comment 2 Mark J. Cox 2004-07-02 03:59:20 EDT

Removing embargo
