Red Hat Product Errata RHSA-2006:0575 0 normal SHIPPED_LIVE Important: Updated kernel packages available for Red Hat Enterprise Linux 4 Update 4 2006-08-10 04:00:00 UTC

Description Mark J. Cox 2006-03-10 10:12:07 UTC 
SUSE discovered a flaw in ACL handling in kernel nfsd; if a filesystem is
exported as read-only the remote user can still set ACLs and they migrate to the
server filesystem.

This issue did not affect the 2.6.9 kernel; however the nfsacl functionality was
introduced into Enterprise Linux 4 in Update 3.  Update 3 contains the patch to
correct this flaw applied to the nfs2acl.c file but it is missing from nfs3acl.c
