CVE-2006-0674 · published 20 years ago
Summary

The arp utility on IBM AIX versions 5.2, 5.2 L, 5.2.2, 5.3, and 5.3 L can be forced to stop working if a local user supplies an overly long iftype argument. This can cause the system or affected services to become unavailable until the process is restarted. Apply the latest IBM AIX security patches or upgrade to a newer AIX release to stop the problem.
