                                        http://security.gentoo.org/

Severity: Normal
Title: Xdg-Utils: Arbitrary command execution
Date: January 30, 2008
Bugs: #207331
ID: 200801-21


Synopsis

A vulnerability has been discovered in Xdg-Utils, allowing for the
remote execution of arbitrary commands.

Background

Xdg-Utils is a set of tools allowing all applications to easily
integrate with the Free Desktop configuration.

Affected packages

-------------------------------------------------------------------
 Package             /  Vulnerable  /                   Unaffected
-------------------------------------------------------------------

1 x11-misc/xdg-utils < 1.0.2-r1 >= 1.0.2-r1

Description

Miroslav Lichvar discovered that the "xdg-open" and "xdg-email" shell
scripts do not properly sanitize their input before processing it.

Impact

A remote attacker could entice a user to open a specially crafted link
with a vulnerable application using Xdg-Utils (e.g. an email client),
resulting in the execution of arbitrary code with the privileges of the
user running the application.

Workaround

There is no known workaround at this time.

Resolution

All Xdg-Utils users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=x11-misc/xdg-utils-1.0.2-r1&quot;
