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 Solution: Apply patches. -- Xi Graphics deXtop CDE 3.0 -- ftp://ftp.xig.com/pub/updates/dextop/3.0/DEX3000.003.tar.gz This patch also fixes an older vulnerability, which can be exploited to escalate privileges: SA8468 -- SCO Open UNIX and UnixWare -- ftp://ftp.sco.com/pub/updates/UnixWare/CSSA-2003-SCO.31/erg712445.pkg.Z Provided and/or discovered by: Discovered by: Kevin Kotas Further information provided by: iDEFENSE Labs Changelog: 2004-08-26: Added another exploit vector in "description" section.
