Here is a list of potential targets that we investigated (they all call
gethostbyname, one way or another), but to the best of our knowledge,
the buffer overflow cannot be triggered in any of them:

apache, cups, dovecot, gnupg, isc-dhcp, lighttpd, mariadb/mysql,
nfs-utils, nginx, nodejs, openldap, openssh, postfix, proftpd,
pure-ftpd, rsyslog, samba, sendmail, sysklogd, syslog-ng, tcp_wrappers,
vsftpd, xinetd.

That being said, we believe it would be interesting if other people
could have a look, just in case we missed something.


That's an impressive list above, thanks!

To add on the topic and aggregate the relevant news in this thread:

Today there's some talk about GHOST possibly being exploitable via web
apps, and in particular via the pingback feature in WordPress:
