Summary

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.
