Description Prasad J Pandit 2013-11-22 08:20:24 EST
Linux kernel built a XFS file system support(CONFIG_XFS_FS) along with the 
Compat mode(CONFIG_COMPAT) enabled, is vulnerable to an invalid pointer 
dereference flaw. It could occur while doing a Compat ioctl call with a
XFS_IOC_ATTRLIST_BY_HANDLE command.

A privileged(CAP_SYS_ADMIN) user/program could use this flaw to either make the system dereference invalid pointer or potentially cause memory corruption.

Comment 5 Petr Matousek 2013-11-26 07:06:06 EST
Statement:

The Red Hat Security Response Team does not consider this issue to be a security flaw due to the full root-like privileges (CAP_SYS_ADMIN) needed for successful exploitation.
