CVE-2013-1819

Published: 6 March 2013

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.

From the Ubuntu security team

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

AuthorNote
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).

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)
