Description of problem: The XFS_IOC_FSGETXATTR ioctl allows unprivileged users to read 12 bytes of uninitialized stack memory, because the fsxattr struct declared on the stack in xfs_ioc_fsgetxattr() does not alter (or zero) the 12-byte fsx_pad member before copying it back to the user. <a href="http://www.linux.sgi.com/archives/xfs-masters/2010-09/msg00002.html">http://www.linux.sgi.com/archives/xfs-masters/2010-09/msg00002.html</a> Acknowledgements: Red Hat would like to thank Dan Rosenberg for reporting this issue.
