Debian LTS Advisory DLA-2403-1 debian-lts@lists.debian.org

Package : rails
Version : 2:4.2.7.1-1+deb9u4
CVE ID : CVE-2020-15169
Debian Bug : 970040
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:
