Debian LTS: DLA-2995-1: smarty3 security update
Summary
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.
