			SCO Security Advisory

Subject:		UnixWare 7.1.4 UnixWare 7.1.3 UnixWare 7.1.1 : x.org possible local socket hijacking
Advisory number: 	SCOSA-2005.8
Issue date: 		2005 January 26
Cross reference:	sr891412 fz530161 erg712694 CAN-2005-0134
______________________________________________________________________________


1. Problem Description

	The socket directories created in /tmp are now required to
	be owned by root and have their sticky-bit set. If the
	permission is not set properly, the component will try to
	set it properly. If it is unable to do that, it will generate 
	error/warning message(s), but the component will not fail.
	(a.k.a. fail softly)

	The owner and permissions of these directories are tried 
	to be set correctly even if X servers are started by regular 
	users; it generates error message if it fails in doing so. 

	The Common Vulnerabilities and Exposures project (cve.mitre.org) 
	has assigned the name CAN-2005-0134 to this issue.
