Version        : 3.1.31+20161214.1.c7d42e4+selfpack1-2+deb9u5
CVE ID         : CVE-2021-21408 CVE-2021-29454
Debian Bug     : 1010375 

Smarty3, a template engine for PHP, allowed template authors to run restricted
static php methods. The same authors could also run arbitrary PHP code by
crafting a malicious math string. If a math string was passed through as user
provided data to the math function, remote users were able to run arbitrary PHP
code as well. 

For Debian 9 stretch, these problems have been fixed in version
3.1.31+20161214.1.c7d42e4+selfpack1-2+deb9u5.

We recommend that you upgrade your smarty3 packages.
