[GLSA]

Gentoo Linux Security Advisory

Title: Horde Application Framework: Remote code execution (GLSA 200604-02)
Severity: high
Exploitable: remote
Date: April 04, 2006
Bug(s): #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: www-apps/horde
Vulnerable: < 3.1.1
Unaffected: >= 3.1.1
Architectures: 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:
