VIM (VIsual editor iMproved) is a version of the vi editor.
A bug was found in the way VIM processes modelines. If a user with modelines enabled opens a text file with a carefully crafted modeline, arbitrary commands may be executed as the user running VIM. The Common Vulnerabilities and Exposures project has assigned the name CAN-2005-2368 to this issue.
Users of VIM are advised to upgrade to these updated packages, which resolve this issue.
