CVE ID         : CVE-2020-8159
Debian Bug     : 960680

ooooooo_q discovered that the actionpack_page-caching Ruby gem, a
static page caching module for Rails, allows an attacker to write
arbitrary files to a web server, potentially resulting in remote code
execution if the attacker can write unescaped ERB to a view.

For Debian 9 stretch, this problem has been fixed in version
1.0.2-4+deb9u1.

We recommend that you upgrade your ruby-actionpack-page-caching packages.
