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
3.1.31+20161214.1.c7d42e4+selfpack1-2+deb9u2.

We recommend that you upgrade your smarty3 packages.
