Malicious websites could abuse smb:// URLs to read or write arbitrary files of the user (CVE-2006-5925). Therefore this update disables SMB support in links.

The links web browser with smbclient installed allows remote attackers to execute arbitrary code via shell metacharacters in an smb:// URI, as demonstrated by using PUT and GET statements.

Corporate 3.0 is not affected by this issue, as that version of links does not have smb:// URI support.

Updated packages have disabled access to smb:// URIs.

Red Hat セキュリティアドバイザリ 2006:0742 から：

セキュリティの脆弱性を修正する更新済みの elinks パッケージが、Red Hat Enterprise Linux 4 で現在利用可能です。

Red Hat セキュリティレスポンスチームは、この更新には重大なセキュリティインパクトがあるものとして評価しています。

Elinks は、モダン Web ページのレンダリングをサポートする、コマンドラインから使用されるテキストモードの Web ブラウザです。

Elinks SMB プロトコルハンドラーに任意のファイルアクセスの欠陥が見つかりました。悪意のある Web ページにより、Elinks が、Elinks を実行するユーザーの権限でファイルを読み取りまたは書き込みさせられる可能性があります。
(CVE-2006-5925)

Elinks の全ユーザーは、この更新済みパッケージにアップグレードし、SMB プロトコルのサポートを Elinks から削除することでこの問題を解決することが推奨されます。

注：この問題は、Red Hat Enterprise Linux 3 に同梱の Elinks パッケージ、または Red Hat Enterprise Linux 2.1 に同梱の Links パッケージには影響しませんでした。

Teemu Salmela discovered that Elinks did not properly validate input when processing smb:// URLs. If a user were tricked into viewing a malicious website and had smbclient installed, a remote attacker could execute arbitrary code with the privileges of the user invoking the program. (CVE-2006-5925)

Jakub Wilk discovered a logic error in Elinks, leading to a buffer overflow. If a user were tricked into viewing a malicious website, a remote attacker could cause a denial of service via application crash, or possibly execute arbitrary code with the privileges of the user invoking the program. (CVE-2008-7224).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

An updated elinks package that corrects a security vulnerability is now available for Red Hat Enterprise Linux 4.

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

Elinks is a text mode Web browser used from the command line that supports rendering modern web pages.

An arbitrary file access flaw was found in the Elinks SMB protocol handler. A malicious web page could have caused Elinks to read or write files with the permissions of the user running Elinks.
(CVE-2006-5925)

All users of Elinks are advised to upgrade to this updated package, which resolves this issue by removing support for the SMB protocol from Elinks.

Note: this issue did not affect the Elinks package shipped with Red Hat Enterprise Linux 3, or the Links package shipped with Red Hat Enterprise Linux 2.1.

來自 Red Hat 安全性公告 2006:0742：

現已提供適用於 Red Hat Enterprise Linux 4 的更新版 elinks 套件，可更正一個安全性弱點。

Teemu Salmela discovered that the links2 character mode web browser performs insufficient sanitising of smb:// URIs, which might lead to the execution of arbitrary shell commands.

The remote host is affected by the vulnerability described in GLSA-200701-27 (ELinks: Arbitrary Samba command execution)

    Teemu Salmela discovered an error in the validation code of 'smb://'     URLs used by ELinks, the same issue as reported in GLSA 200612-16     concerning Links.
  Impact :

    A remote attacker could entice a user to browse to a specially crafted     'smb://' URL and execute arbitrary Samba commands, which would allow     the overwriting of arbitrary local files or the upload or download of     arbitrary files. This vulnerability can be exploited only if     'smbclient' is installed on the victim's computer, which is provided by     the 'samba' Gentoo package.
  Workaround :

    There is no known workaround at this time.
