Yes

Security database references:

In the Debian bugtracking system: Bug 1010375.
In Mitre's CVE dictionary: CVE-2021-21408, CVE-2021-29454.

More information:

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.
