The Netrw plugin 125 in netrw.vim in Vim 7.2a.10 allows user-assisted attackers to execute arbitrary code via shell metacharacters in filenames used by the execute and system functions within the (1) mz and (2) mc commands, as demonstrated by the netrw.v2 and netrw.v3 test cases. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2008-2712.

From Red Hat Security Advisory 2008:0580 :

Updated vim packages that fix security issues are now available for Red Hat Enterprise Linux 5.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

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.

The VI Improved editor (vim) was updated to version 7.2.108 to fix various security problems and other bugs.

CVE-2008-4677: The netrw plugin sent credentials to all servers.
CVE-2009-0316: The python support used a search path including the current directory, allowing code injection when python code was used.
CVE-2008-2712: Arbitrary code execution in vim helper plugins filetype.vim, zipplugin, xpm.vim, gzip_vim, and netrw were fixed.
CVE-2008-3074: tarplugin code injection CVE-2008-3075: zipplugin code injection CVE-2008-3076: several netrw bugs, code injection CVE-2008-6235: code injection in the netrw plugin CVE-2008-4677:

Several vulnerabilities were found in the vim editor :

A number of input sanitization flaws were found in various vim system functions. If a user were to open a specially crafted file, it would be possible to execute arbitrary code as the user running vim (CVE-2008-2712).

Ulf H&Atilde;&curren;rnhammar of Secunia Research found a format string flaw in vim's help tags processor. If a user were tricked into executing the helptags command on malicious data, it could result in the execution of arbitrary code as the user running vim (CVE-2008-2953).

A flaw was found in how tar.vim handled TAR archive browsing. If a user were to open a special TAR archive using the plugin, it could result in the execution of arbitrary code as the user running vim (CVE-2008-3074).

A flaw was found in how zip.vim handled ZIP archive browsing. If a user were to open a special ZIP archive using the plugin, it could result in the execution of arbitrary code as the user running vim (CVE-2008-3075).

A number of security flaws were found in netrw.vim, the vim plugin that provides the ability to read and write files over the network. If a user opened a specially crafted file or directory with the netrw plugin, it could result in the execution of arbitrary code as the user running vim (CVE-2008-3076).

A number of input validation 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 arbitary code as the user running vim (CVE-2008-4101).

A vulnerability was found in certain versions of netrw.vim where it would send FTP credentials stored for an FTP session to subsequent FTP sessions to servers on different hosts, exposing FTP credentials to remote hosts (CVE-2008-4677).

This update provides vim 7.2 (patchlevel 65) which corrects all of these issues and introduces a number of new features and bug fixes.

Update :

The previous vim update incorrectly introduced a requirement on libruby and also conflicted with a file from the git-core package (in contribs). These issues have been corrected with these updated packages.

Several vulnerabilities have been found in vim, an enhanced vi editor.
The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2008-2712     Jan Minar discovered that vim did not properly sanitise     inputs before invoking the execute or system functions     inside vim scripts. This could lead to the execution of     arbitrary code.

  - CVE-2008-3074     Jan Minar discovered that the tar plugin of vim did not     properly sanitise the filenames in the tar archive or     the name of the archive file itself, making it prone to     arbitrary code execution.

  - CVE-2008-3075     Jan Minar discovered that the zip plugin of vim did not     properly sanitise the filenames in the zip archive or     the name of the archive file itself, making it prone to     arbitrary code execution.

  - CVE-2008-3076     Jan Minar discovered that the netrw plugin of vim did     not properly sanitise the filenames or directory names     it is given. This could lead to the execution of     arbitrary code.

  - CVE-2008-4101     Ben Schmidt discovered that vim did not properly escape     characters when performing keyword or tag lookups. This     could lead to the execution of arbitrary code.

Jan Minar reports :

Applying the ``D'' to a file with a crafted file name, or inside a directory with a crafted directory name, can lead to arbitrary code execution.

Lack of sanitization throughout Netrw can lead to arbitrary code execution upon opening a directory with a crafted name.

The Vim Netrw Plugin shares the FTP user name and password across all FTP sessions. Every time Vim makes a new FTP connection, it sends the user name and password of the previous FTP session to the FTP server.
