Detail

A security issue affects the following Ubuntu releases:

Ubuntu 4.10 (Warty Warthog) Ubuntu 5.04 (Hoary Hedgehog)

The following packages are affected:

kvim kvim-perl kvim-python kvim-tcl vim vim-gnome vim-gtk vim-lesstif vim-perl vim-python vim-tcl

The problem can be corrected by upgrading the affected package to version 1:6.3-025+1ubuntu2.3 (for Ubuntu 4.10), or 1:6.3-046+1ubuntu7.1 (for Ubuntu 5.04). In general, a standard system upgrade is sufficient to effect the necessary changes.

Details follow:

Georgi Guninski discovered that it was possible to construct Vim modelines that execute arbitrary shell commands by wrapping them in glob() or expand() function calls. If an attacker tricked an user to open a file with a specially crafted modeline, he could exploit this to execute arbitrary commands with the user's privileges.
