SCO OpenServer 5.0.6 (and possibly earlier versions) ships with several suid bin executables used in printer administration and related tasks.
This includes lpforms, a component used to manage and configure print destinations, devices and printer interface programs.
'lpforms' contains a locally exploitable buffer overflow vulnerability. If a command line parameter argument is of excessive length, a stack overflow condition will occur.
An attacker may exploit this vulnerability execute arbitrary code with effective user 'bin' privileges.
