Here are the details from the Slackware 10.0 ChangeLog:
+--------------------------+
patches/packages/getmail-4.2.0-noarch-1.tgz: Upgraded to
 getmaii-4.2.0. Earlier versions contained a local security flaw
 when used in an insecure fashion (surprise, running something as
 root that writes to user-controlled files or directories could
 allow the old symlink attack to clobber system files! :-)
 From the getmail CHANGELOG:
 This vulnerability is not exploitable if the administrator does
 not deliver mail to the maildirs/mbox files of untrusted local
 users, or if getmail is configured to use an external
 unprivileged MDA. This vulnerability is not remotely exploitable.
 Most users would not use getmail in such as way as to be vulnerable
 to this flaw, but if your site does this package closes the hole.
 I'd also recommend not using getmail like this. Either run it as the
 user that owns the target mailbox, or deliver through an external MDA.
 (* Security fix *)
