Here are the details from the Slackware 9.0 ChangeLog:
+--------------------------+
Mon Aug 25 15:35:28 PDT 2003
patches/packages/infozip-5.50-i486-2.tgz: Fixed a bug where a specially
 crafted archive might try to write to ../ or ../../, etc, potentially
 overwriting system files if the user (such as root) has permissions to
 overwrite them. Thanks to jelmer for locating this problem, and
 Ben Laurie for providing a patch.
 (* Security fix *)
