Debian DLA-2403-1 : rails security update

medium Nessus Plugin ID 141379

Language:

Synopsis

The remote Debian host is missing a security update.

Description

A potential Cross-Site Scripting (XSS) vulnerability was found in rails, a ruby based MVC framework. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped.

For Debian 9 stretch, this problem has been fixed in version 2:4.2.7.1-1+deb9u4.

We recommend that you upgrade your rails packages.

For the detailed security status of rails please refer to its security tracker page at: https://security-tracker.debian.org/tracker/rails

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 packages.
