Debian DLA-1986-1 : ruby-haml security update

medium Nessus Plugin ID 130771

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected ruby-haml package.
