Package        : ruby-kramdown
Version        : 1.12.0-1+deb9u1
CVE ID         : CVE-2020-14001
Debian Bug     : 965305

ruby-kramdown processes the template option inside Kramdown documents by
default, which allows unintended read access (such as
template="/etc/passwd") or unintended embedded Ruby code execution (such
as a string that begins with template="string://<%= `). NOTE: kramdown is
used in Jekyll, GitLab Pages, GitHub Pages, and Thredded Forum.

For Debian 9 stretch, this problem has been fixed in version
1.12.0-1+deb9u1.

We recommend that you upgrade your ruby-kramdown packages.
