CVE ID:	CVE-2010-1636
Description:	The btrfs_ioctl_clone function in fs/btrfs/ioctl.c in the btrfs functionality in the Linux kernel 2.6.29 through 2.6.32, and possibly other versions, does not ensure that a cloned file descriptor has been opened for reading, which allows local users to read sensitive information from a write-only file descriptor.
Test IDs:	1.3.6.1.4.1.25623.1.0.67576   1.3.6.1.4.1.25623.1.0.67501
