Package        : smarty3
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
3.1.31+20161214.1.c7d42e4+selfpack1-2+deb9u2.

We recommend that you upgrade your smarty3 packages.
