Version : 3.1.31+20161214.1.c7d42e4+selfpack1-2+deb9u2
CVE ID : CVE-2018-13982 CVE-2021-26119 CVE-2021-26120
Several vulnerabilities were discovered in smarty3, a template engine
for PHP.
CVE-2018-13982
path traversal vulnerability due to insufficient sanitization of
code in Smarty templates. This allows attackers controlling the
Smarty template to bypass the trusted directory security
restriction and read arbitrary files.
CVE-2021-26119
allows a Sandbox Escape because $smarty.template_object can be
accessed in sandbox mode.
CVE-2021-26120
allows code injection vulnerability via an unexpected function
name after a {function name= substring.
For Debian 9 stretch, these problems have been fixed in version

We recommend that you upgrade your smarty3 packages.
