Description Prasad J Pandit 2015-03-24 04:25:48 EDT 
Linux kernel built with the Btrfs Filesystem support(CONFIG_BTRFS_FS) is
vulnerable to a race condition which leaves the extended attribute(xattr)
empty for a short time window. This could be leveraged to bypass set ACLs
and potentially escalate user privileges.

An unprivileged user could use this flaw to potentially escalate privileges on
a system.

Comment 1 Prasad J Pandit 2015-03-24 04:28:53 EDT 
Statement:

This issue does not affect the versions of the kernel package as shipped with
Red Hat Enterprise Linux 5 and Red Hat Enterprise MRG 2.

This issue affects the version of Linux kernel as shipped with Red Hat Enterprise Linux 6 and 7. Future kernel updates for Red Hat Enterprise Linux 7 may address this issue.

Given the Moderate impact and the fact that BRTFS file system is no longer Technology preview in Red Hat Enterprise Linux 6 this issue is not currently planned to be addressed in future releases of Red Hat Enterprise Linux 6.
