-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ 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. 2.
