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.
