"Updated vim packages that fix a security issue are now available for
Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

VIM (VIsual editor iMproved) is a version of the vi editor.

An arbitrary command execution flaw was found in the way VIM processes
modelines. If a user with modelines enabled opened a text file
containing a carefully crafted modeline, arbitrary commands could be
executed as the user running VIM. (CVE-2007-2438)

Users of VIM are advised to upgrade to these updated packages, which
resolve this issue.

Please note: this issue did not affect VIM as distributed with Red Hat
Enterprise Linux 2.1, 3, or 4."
