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 tar archive and possibly (2) the filename of the first file in a tar archive, which is not properly handled by the VIM TAR plugin (tar.vim) v.10 through v.22, as demonstrated by the shellescape, tarplugin.v2, tarplugin, and tarplugin.updated test cases. NOTE: this issue reportedly exists because of an incomplete fix for CVE-2008-2712. NOTE: this issue has the same root cause as CVE-2008-3075. NOTE: due to the complexity of the associated disclosures and the incomplete information related to them, there may be inaccuracies in this CVE description and in external mappings to this identifier.

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)

SL3 and SL4 Only: A heap-based overflow flaw was discovered in Vim's expansion of file name patterns with shell wildcards. An attacker could create a specially crafted file or directory name that, when opened by Vim, caused the application to crash or, possibly, execute arbitrary code. (CVE-2008-3432)

SL5 Only: 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)

SL5 Only: 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)

SL5 Only: 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)

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.

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.

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.

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2008:0580 advisory.

  - vim format string flaw (CVE-2007-2953)

  - vim: command execution via scripts not sanitizing inputs to execute and system (CVE-2008-2712)

  - Vim zip.vim plugin: improper Implementation of shellescape() (arbitrary code execution) (CVE-2008-3075)

  - vim: arbitrary code execution in commands: K, Control-], g] (CVE-2008-4101)

  - Vim netrw.vim plugin: lack of sanitization throughout netrw.vim can lead to arbitrary code execution     (CVE-2008-6235)
