CVE-2014-10067 is a medium-severity flaw (CVSS 5.9) affecting paypal-ipn. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

paypal-ipn before 3.0.0 uses the `test_ipn` parameter (which is set by the PayPal IPN simulator) to determine if it should use the production PayPal site or the sandbox. With a bit of time, an attacker could craft a request using the simulator that would fool any application which does not explicitly check for test_ipn in production.

Remotely exploitable, no login, no user action

A fixed release or distro patch exists.
