CVE-2014-7283 (retired)

Priority
Description
The xfs_da3_fixhashpath function in fs/xfs/xfs_da_btree.c in the xfs
implementation in the Linux kernel before 3.14.2 does not properly compare
btree hash values, which allows local users to cause a denial of service
(filesystem corruption, and OOPS or panic) via operations on directories
that have hash collisions, as demonstrated by rmdir operations.
Ubuntu-Description
Hannes Frederic Sowa reported a hash collision ordering problem in the xfs
filesystem in the Linux kernel. A local user could exploit this flaw to
cause filesystem corruption and a denial of service (oops or panic).
