vim security update

CentOS Errata and Security Advisory CESA-2008:0580

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 Harnhammar, 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.
