CVE-2013-1819

Priority
Description
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.
Ubuntu-Description
A failure to validate block numbers was discovered in the Linux kernel's
implementation of the XFS filesystem. A local user can cause a denial of
service (system crash) if they can mount, or cause to be mounted a
corrupted or special crafted XFS filesystem.
Notes
henrixThis 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).
