The _xfs_buf_find function in fs/xfs/xfs_buf.c in the Linux kernel before
3.7.6 does not validate block numbers, which allows local users to cause a
denial of service (NULL pointer dereference and system crash) or possibly
have unspecified other impact by leveraging the ability to mount an XFS
filesystem containing a metadata inode with an invalid extent map.

Notes

Author	Note
henrix	This CVE has minor impact as it requires root privileges to mount a corrupted image. Also, it is too risky to backport the fix to older kernels (Precise, in this case).
jjohansen	precise_linux and precise_linux-lts-quantal ignored (was in USN-1968-1/3.2.0-54.82 reverted minor priority CVE with high risk of regression in backport) precise_linux-armadaxp ignored due to high risk of regression in backport
