Gentoo Linux Security Advisory

Title: Xdg-Utils: Arbitrary command execution (GLSA 200801-21)
Severity: normal
Exploitable: remote
Date: January 30, 2008
Bug(s): #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: x11-misc/xdg-utils
Vulnerable: < 1.0.2-r1
Unaffected: >= 1.0.2-r1
Architectures: All supported architectures


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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=x11-misc/xdg-utils-1.0.2-r1"
