A ruby-haml security update has been released for Debian GNU/Linux 8 LTS (Jessie)

Package : ruby-haml
Version : 4.0.5-2+deb8u1
CVE ID : CVE-2017-1002201

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.
