Title: Three SCO Security Advisories
Abstract:
Vendors affected: SCO
Operating systems affected: SCO
Applications affected: SCO
Title
=====
Three SCO Security Advisories:
1. OpenServer 5.0.6 OpenServer 5.0.7 : cosessoin local privilege elevation
2. OpenServer 5.0.6 OpenServer 5.0.7 : wu-ftp local users can bypass access
Restrictions
3. UnixWare 7.1.4 UnixWare 7.1.3 UnixWare 7.1.1 : x.org possible local
socket hijacking
Detail
======
1. A problem has been identified in the scosession program
when handling strings on the commandline. Because of this,
a local attacker may be able to gain elevated privileges.
The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2003-1021 to this issue.
2. wu-ftpd 2.6.2 and earlier, with the restricted-gid option enabled, allows local users to bypass access restrictions by changing the permissions to prevent access to their home directory, which causes wu-ftpd to use the root directory instead.
The Common Vulnerabilities and Exposures project (cve.mitre.org)
has assigned the name CAN-2004-0148 to this issue.
3. 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.
