Description of problem:
Jan Minar has reported the following problem present in Vim shellescape()
function implementation and demonstrated by testcases in zip.vim plugin:
The implementation of the shellescape() function does not properly
escape all special items, in particular the '!' character). This
can result in untrusted data being insufficiently sanitized
and possibly lead to arbitrary code execution.
To show this vulnerability can be exploited, the tar.vim plugin test cases
has been updated (zipplugin and zipplugin.v2 test cases).
CVE-2008-3075 as been pre-assigned and used in rPath advisory:

mention about zipplugin should be removed from CVE-2008-2712.

Common Vulnerabilities and Exposures assigned an identifier CVE-2008-3075 to
the following vulnerability:
The shellescape function in Vim 7.0 through 7.2, including 7.2a.10,
allows user-assisted attackers to execute arbitrary code via the "!"
(exclamation point) shell metacharacter in (1) the filename of a ZIP
archive and possibly (2) the filename of the first file in a ZIP
archive, which is not properly handled by zip.vim in the VIM ZIP
plugin (zipPlugin.vim) v.11 through v.21, as demonstrated by the
zipplugin and zipplugin.v2 test cases. NOTE: this issue reportedly
exists because of an incomplete fix for CVE-2008-2712. NOTE: this
