Nov 6 01:24:44 mail nscd: [ID 461630 user.crit] gethostans: possible attempt to exploit buffer overflow while looking up linux.somesite.com.my
OS: Solaris 9
The above is the warning message I found in /var/adm/messages few days back. And there's only one of it.
May I know exactly what is this? I was told that the malicious attempt (if there's one) could hang the system. Is there any patches or setting I can set to prevent such attempt to occur?
The system is still running fine but prevention is better than cure.
