TITLE:
Xfce Terminal "Open Link" Command Injection Security Issue

SECUNIA ADVISORY ID:
SA26037

VERIFY ADVISORY:
http://secunia.com/advisories/26037/

CRITICAL:
Not critical

IMPACT:
Security Bypass

WHERE:
>From remote

SOFTWARE:
Xfce Terminal 0.x
http://secunia.com/product/14777/

DESCRIPTION:
Lasse Kärkkäinen has reported a security issue in Xfce Terminal,
which can be exploited by malicious people to inject shell commands.

The "terminal_helper_execute()" function in terminal/terminal.c uses
"/bin/sh -c" to spawn the browser process. This can be used to
disclose sensitive information or execute shell commands by e.g.
tricking a user into opening a malicious link using the "Open Link"
functionality.

The security issue is confirmed in version 0.2.6 for Fedora Core 6
and Mozilla Firefox as default browser. Other versions may also be
affected.

SOLUTION:
Do not open malicious URLs.
