Jason, Assuming that the vendor ships the kerberos development packages, something like this might be what you want: krb5-config --version Kerberos 5 release 1.4.4 A cursory look would tell you that I am vulnerable to a heap of CVEs related to Kerberos. However, in my case I am running Debian Etch. Debian has a policy of not introducing new upstream versions just to patch security fixes, so they always do targeted security fixes. So, the version installed on my machine is something like this: apt-cache policy libkrb5-dev |grep Installed Installed: 1.4.4-7etch4 Looking at the package changelog, there are several entries (4, in fact) like this: krb5 (1.4.4-7etch4) stable-security; urgency=emergency * Fix bug in fix for CVE-2007-3999: the previous patch could allow an overflow of up to 32 bytes. Depending on how locals are layed out on the stack, this may or may not be a problem. -- Sam Hartman <[EMAIL PROTECTED]> Tue, 04 Sep 2007 19:51:49 -0400 The total number of CVEs noted in the changelog for the current release is six. So, while a look at the raw version number as reported by Kerberos looks bad, further infestigation shows that I am OK in that department (assuming there have only been six CVEs total since the release of 1.4.4; I have not checked). So, I guess it depends in part on your Unix vendor's security policy. Since you are .mil, you are most probably using Solaris. I know that Sun deploys packages (you can access information about them using pkginfo), but that about exhausts my knowledge of Solaris-specific sysadmin knowledge. So, if sun ships detailed changelogs with their packages (like Debian does), you might be able to glean the necessary information from there. Regards, -Roberto -- Roberto C.
