SCO OpenServer 5.0.6 lpadmin Buffer Overflow Vulnerability (EDBID:20735)

SCO OpenServer 5.0.6 (and possibly earlier versions) ships with several suid 'bin' executables used in printer administration and related tasks.

This includes lpadmin, a component used to manage and configure print destinations, devices and printer interface programs.

'lpadmin' contains a locally exploitable buffer overflow condition present in the handling of command-line parameters.

If properly exploited, this can yield user 'bin' privileges to the attacker. 

/opt/K/SCO/Unix/5.0.6Ga/usr/lib/lpadmin `perl -e 'print "A" x 7000'`

Memory fault - core dumped

SCO OpenServer lpadmin First Argument Local Overflow
Local Access Required Input Manipulation
Loss of Integrity

- 漏洞描述

A local overflow exists in OpenServer. The lpadmin command fails to validate user-supplied arguments resulting in a buffer overflow. With a specially crafted request of more than 6476 characters, an attacker can cause arbitrary code execution resulting in a loss of integrity.
