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)
Multiple security flaws were found in netrw.vim, the Vim plug-in providing file reading and writing over the network. If a user opened a specially crafted file or directory with the netrw plug-in, it could result in arbitrary code execution as the user running Vim. (CVE-2008-3076)
A security flaw was found in zip.vim, the Vim plug-in that handles ZIP archive browsing. If a user opened a ZIP archive using the zip.vim plug-in, it could result in arbitrary code execution as the user running Vim. (CVE-2008-3075)
A security flaw was found in tar.vim, the Vim plug-in which handles TAR archive browsing. If a user opened a TAR archive using the tar.vim plug-in, it could result in arbitrary code execution as the user runnin Vim. (CVE-2008-3074)
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.
