.: Description
SCO OpenServer 5.0.6 ships with suid bin=20
/opt/K/SCO/Unix/5.0.6Ga/usr/lib/lpforms.
lpforms has poor handling of command line arguments resulting in a buffer=20
overflow.
lpforms will core dump if fed more than 6240 chars.
.: Impact
/opt/K/SCO/Unix/5.0.6Ga/usr/lib/lpforms `perl -e 'print "A" x 7000'`
Memory fault - core dumped
This problem makes it possible to overwrite memory space of the running=20
process,
and potentially execute code with the inherited privileges of bin.
.: Workaround
.: Systems Affected
SCO OpenServer 5.0.6 upgrade from 5.0.x and 5.0.6 fresh install.
chmod -s /opt/K/SCO/Unix/5.0.6Ga/usr/lib/lpforms
.: Proof of Concept
To be released at a later time.
.: Vendor Status
Vendor was notified on 03/22/01. Vendor lab tests confirmed the issue. Patch
status is unknown.
