TITLE:
Xdg-utils mailcap Command Execution Security Issue

SECUNIA ADVISORY ID:
SA33407

VERIFY ADVISORY:
http://secunia.com/advisories/33407/

CRITICAL:
Moderately critical

IMPACT:
System access

WHERE:
>From remote

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

DESCRIPTION:
A security issue in Xdg-utils has been reported, which can be
exploited by malicious people to compromise a user's system.

The problem is caused when Xdg-open is used in a mailcap file to open
files with user preferred applications. This can be exploited to
execute arbitrary commands on a user's system e.g. when a specially
crafted .desktop file with a safe MIME type is sent to Firefox.

Successful exploitation requires that a system is configured to open
certain MIME types with Xdg-open e.g. via a mailcap file.

NOTE: This may also be exploitable via other applications that use a
mailcap file to open files.

SOLUTION:
Do not invoke Xdg-open via a mailcap file.
