More information:

In haml, when using user input to perform tasks on the server, characters like <> " ' must be escaped properly. In this case, the ' character was missed. An attacker can manipulate the input to introduce additional attributes, potentially executing code.

For Debian 8 Jessie, this problem has been fixed in version 4.0.5-2+deb8u1.

We recommend that you upgrade your ruby-haml packages.
