GLSA 200604-02: Horde Application Framework: Remote code execution

http://security.gentoo.org/

Severity:	high
Title:	Horde Application Framework: Remote code execution
Date:	04/04/2006
Bugs:	#127889, #126435
ID:	200604-02

Synopsis

The help viewer of the Horde Framework allows attackers to execute arbitrary remote code.

Background

The Horde Application Framework is a general-purpose web application framework written in PHP, providing classes for handling preferences, compression, browser detection, connection tracking, MIME and more.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
www-apps/horde	< 3.1.1	>= 3.1.1	All supported architectures

Description

Jan Schneider of the Horde team discovered a vulnerability in the help viewer of the Horde Application Framework that could allow remote code execution (CVE-2006-1491). Paul Craig reported that "services/go.php" fails to validate the passed URL parameter correctly (CVE-2006-1260).

Impact

An attacker could exploit the vulnerability in the help viewer to execute arbitrary code with the privileges of the web server user. By embedding a NULL character in the URL parameter, an attacker could exploit the input validation issue in go.php to read arbitrary files.

Workaround

There are no known workarounds at this time.

Resolution

All Horde Application Framework users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/horde-3.1.1"
