SECUNIA ADVISORY ID:
SA30731

VERIFY ADVISORY:
http://secunia.com/advisories/30731/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Vim 7.x

DESCRIPTION:
Jan Minar has reported some vulnerabilities in Vim, which can be
exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to the "filetype.vim", "tar.vim",
"zip.vim", "xpm.vim", "xpm2.vim", "gzip.vim", and "netrw.vim" scripts
improperly escaping special characters contained within filenames
passed to the "execute" statement. This can be exploited to execute
arbitrary commands on an affected system by tricking the user into
opening specially crafted files.

The vulnerabilities are reported in versions 6.4 and 7.1.298. Other
versions may also be affected.

SOLUTION:
Do not open untrusted files using Vim.

The vendor recommends applying patch 7.1.299 and updating to the
latest runtime files, which fix some of the reported
vulnerabilities.
