cvechecker updates

The in-svn version of cvechecker has seen quite a few changes in the last few days. I’m adding support for MySQL to it. This support will be added in three steps:

  1. support the same features as cvechecker currently does using sqlite
  2. streamline the database code so that duplicate code in the sqlite implementation and mysql implementation is removed
  3. support multi-node systems with a single master database

The latter is something I’ve been meaning to implement for quite some time: have a single system dedicated to download and store the latest CVE entries in the database (as well as CPE definitions) whereas several systems can use the database by storing their own system information and getting a mapping from that information against the CVE database. Even more so, it would allow you to query the database asking on which systems a particular software was detected, or which systems still have vulnerable software installed.

When the MySQL support is implemented, I’m going to work a bit on the versions.dat file, because it doesn’t really support many services currently. I’m going to use it against my “virtual network” (a combination of KVM guests running bind (master/slave), ldap (multi-master), postfix, apache, squirrelmail, courier, postgresql, mysql and more) and enhance it so that it detects all those components as well.

Oh, btw, I had a request to include support for just telling cvechecker which components/software to look for (rather than it scanning the files and deducing it from regular expressions and the like). The in-svn version supports it, so it will definitely be part of the 3.0 release.
