Description:
A vulnerability has been reported in CDE (Common Desktop Environment), which can be exploited by malicious, local users to escalate their privileges.
The vulnerability is caused due to a boundary error in CDE libDtHelp when handling the "DTHELPUSERSEARCHPATH" environment variable. This can be exploited via suid application linked to libDtHelp (eg. dtprintinfo) to cause a buffer overflow by inserting an overly long, specially crafted string and then invoking Help.
This can also be exploited using the "LOGNAME" environment variable.
The vulnerability affects the following products:
* Xi Graphics deXtop CDE 3.0
* SCO Open UNIX 8.0.0
* SCO UnixWare 7.1.3 and 7.1.1
