Description

The remote Debian 9 host has a package installed that is affected by multiple vulnerabilities as referenced in the dla-2995 advisory.

- Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to versions 3.1.43 and 4.0.3, template authors could run restricted static php methods. Users should upgrade to version 3.1.43 or 4.0.3 to receive a patch. (CVE-2021-21408)

- Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to versions 3.1.42 and 4.0.2, template authors could 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, external users could run arbitrary PHP code by crafting a malicious math string. Users should upgrade to version 3.1.42 or 4.0.2 to receive a patch. (CVE-2021-29454)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the smarty3 packages.

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