vim - security update

Florian Larysch and Bram Moolenaar discovered that vim, an enhanced vi
editor, does not properly validate values for the the filetype,
syntax and keymap options, which may result in the execution of
arbitrary code if a file with a specially crafted modeline is opened.

For Debian 7 Wheezy, these problems have been fixed in version
2:7.3.547-7+deb7u1.

We recommend that you upgrade your vim packages.
