3. Description:

Vim (Visual editor IMproved) is an updated and improved version of the vi
editor.

Several input sanitization flaws were found in Vim's keyword and tag
handling. If Vim looked up a document's maliciously crafted tag or keyword,
it was possible to execute arbitrary code as the user running Vim.
(CVE-2008-4101)

A heap-based overflow flaw was discovered in Vim's expansion of file name
patterns with shell wildcards. An attacker could create a specially-crafted
file or directory name that, when opened by Vim, caused the application to
crash or, possibly, execute arbitrary code. (CVE-2008-3432)

Several input sanitization flaws were found in various Vim system
functions. If a user opened a specially crafted file, it was possible to
execute arbitrary code as the user running Vim. (CVE-2008-2712)

Ulf Härnhammar, of Secunia Research, discovered a format string flaw in
Vim's help tag processor. If a user was tricked into executing the
"helptags" command on malicious data, arbitrary code could be executed with
the permissions of the user running Vim. (CVE-2007-2953)

All Vim users are advised to upgrade to these updated packages, which
contain backported patches to correct these issues.
