IBM AIX nslookup hostname buffer overflow
|aix-nslookup-hostname-bo (8031)||High Risk|
Nslookup is vulnerable to a buffer overflow, caused by improper bounds checking of the hostname that is being queried. By sending an overly long hostname to nslookup, a local attacker could overflow a buffer and execute arbitrary code on the system with root privileges.
