The xfs_swapext function in fs/xfs/xfs_dfrag.c in the Linux kernel before 2.6.35 does not properly check the file descriptors passed to the SWAPEXT ioctl, which allows local users to leverage write access and obtain read access by swapping one file into another file.

Statement

Enterprise Linux 3, 4 and Red Hat Enterprise MRG as they did not include
support for the XFS filesystem. A future kernel update in Red Hat Enterprise
Linux 5 will address this issue.
