TITLE:
Xdg-utils Command Injection Vulnerabilities

SECUNIA ADVISORY ID:
SA28638

VERIFY ADVISORY:
http://secunia.com/advisories/28638/

CRITICAL:
Less critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Xdg-utils 1.x
http://secunia.com/product/17393/

DESCRIPTION:
Some vulnerabilities have been reported in Xdg-utils, which can be
exploited by malicious people to compromise a user's system.

The vulnerabilities are caused due to the "xgd-open" and "xdg-email"
scripts not correctly sanitising parameters before using them in a
sed call. This can be exploited to inject and execute shell commands
if e.g. a malicious URL is passed to the affected scripts.

Successful exploitation requires that the scripts are not used in a
KDE, Gnome, or XFCE session.

The vulnerabilities are reported in version 1.0.2. Other versions may
also be affected.

SOLUTION:
Fixed in the CVS repository:
http://webcvs.freedesktop.org/portland/portland/xdg-utils/scripts/xdg-email?r1=1.36&r2=1.37
http://webcvs.freedesktop.org/portland/portland/xdg-utils/scripts/xdg-open?r1=1.32&r2=1.33

PROVIDED AND/OR DISCOVERED BY:
Reported in a Red Hat bug by Miroslav Lichvar.
