Denial of service via local system, User access via local system, error|
Exploit Included: Yes |
Version(s): SCO 5.0.6|
Secure Network Operations Strategic Reconnaissance Team issued several advisories for vulnerabilities in SCO UNIX utilities and applications, including lpusers, lpshut, lpadmin, lpforms, recon, and sendmail.|
It is reported that SCO OpenServer 5.0.6 ships with /opt/K/SCO/Unix/5.0.6Ga/usr/bin/recon configured as set userid "root". In addition, recon contains a buffer overflow in its handling of command line arguments that will trigger if supplied with more than 1315 characters.
Vendor has reportedly been notified.
A local user can cause the recon application to crash and may be able to cause arbitrary code to be executed on the server with root-level privileges.|
No solution was available at the time of this entry.|
