TITLE:
renattach "pipe" Potential Shell Command Injection Security Issue

SECUNIA ADVISORY ID:
SA12778

VERIFY ADVISORY:
http://secunia.com/advisories/12778/

CRITICAL:
Not critical

IMPACT:
Unknown

WHERE:
From remote

SOFTWARE:
renattach 1.x
http://secunia.com/product/4028/

DESCRIPTION:
A security issue has been reported in renattach, which has an unknown
impact, but potentially could allow execution of arbitrary commands.

The problem is that the pipe functionality is provided in an insecure
way, which potentially can be exploited to inject arbitrary shell
commands.

Successful exploitation requires that the "-p" or "--pipe" command
line option is used.

The security issue has been reported in version 1.2.0 and 1.2.1.

NOTE: According to the vendor, there does not seem to be a practical
way of exploiting the vulnerability for arbitrary command execution.

SOLUTION:
Update to version 1.2.2.
