Title: AIX nslookup Vulnerability
Severity: MODERATE
Description:
The nslookup command which ships with AIX 4.1.* and AIX 4.2 has a vulnerability which allows local users to become root. If nslookup is installed with the s-bit all users can create and overwrite files owned by root. This works in the interactive mode, when dumping dns-records to a file (with ls -d DOMAINNAME > FILE for example). This was tested on aix 4.2.0, 4.2.1 and 4.1.1, where nslookup is installed suid-root by default.
