COMMAND
	xfsdump insecure file creation
SYSTEMS AFFECTED
	versions prior to 2.2.8
PROBLEM
	As reported in Debian Security Advisory DSA 283-1:
	
	Ethan Benson discovered a problem in xfsdump, that contains
	administrative utilities for the XFS filesystem. When filesystem quotas
	are enabled xfsdump runs xfsdq to save the quota information into a
	file at the root of the filesystem being dumped. The manner in which
	this file is created is unsafe.
	
	While fixing this, a new option ``-f path'' has been added to xfsdq(8)
	to specify an output file instead of using the standard output stream.
	This file is created by xfsdq and xfsdq will fail to run if it exists
	already. The file is also created with a more appropriate mode than
	whatever the umask happened to be when xfsdump(8) was run.
SOLUTION
	upgrade to the latest available in your distribution / at your vendor.
