Need help identifiying security vuln. w/ listed versions of software


I recently took over programming for a semi-large website. They are currently using a web-design / hosting company to manage their server. They are running RH 7.3 and it looks like the system has not been updated in quite some time. Can you tell me how I might take the version numbers of the things listed below and find out if there are any security vulnerabilites. Thank!

The following ports are open on this webserver:


I am not really familiar with ip chains, but this looks like everything is accepted:

Chain input (policy ACCEPT):
target prot opt source destination ports
ACCEPT tcp -y---- anywhere anywhere any -> ssh
ACCEPT tcp -y---- anywhere anywhere any -> smtp
ACCEPT tcp -y---- anywhere anywhere any -> http
ACCEPT tcp -y---- anywhere anywhere any -> ftp
ACCEPT all ------ anywhere anywhere n/a
ACCEPT all ------ anywhere anywhere n/a
ACCEPT udp ------ anywhere domain -> any
REJECT tcp -y---- anywhere anywhere any -> any
REJECT udp ------ anywhere anywhere any -> any
Chain forward (policy ACCEPT):
Chain output (policy ACCEPT):

Here are the versions of pertinent programs:

Distro: RH 7.3
Kernel: 2.4.18-3
Apache: 1.3.28
NcFTP 3.1.3/985
OpenSSH_3.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f
Postfix: 1.1.12
ipopd: not sure how to find out
imapd: not sure how to find out

I'd check either one of the vuln databases (securityfocus / CVE , etc) or consult the specific vendor. Most will have reasonably good security related alerts, for example here's Apaches:

which shows your version to have multiple vulns as does your kernel (which has some real nasty bugs like mremap and do_brk). If it's been unpatched that long, you might want to consider hosing it and installing something that can be easily updated (like fedora). I'd be too concerned about possible compromise to just try and patch and pray.

Is it possible that these programs have been updated/patched without the version information being updated?

I just don't want to approach the ISP techs with a "this machine is a security risk" and have them laugh in my face.

Thank you for your post, you pointed me in the right direction.
