Debian DSA-5151-1 : smarty3 - security update

critical Nessus Plugin ID 161686

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 10 / 11 host has a package installed that is affected by multiple vulnerabilities as referenced in the dsa-5151 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 before 3.1.39 allows a Sandbox Escape because $smarty.template_object can be accessed in sandbox mode. (CVE-2021-26119)

- Smarty before 3.1.39 allows code injection via an unexpected function name after a {function name= substring. (CVE-2021-26120)

- 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)

- Smarty is a template engine for PHP, facilitating the separation of presentation (HTML/CSS) from application logic. Prior to versions 3.1.45 and 4.1.1, template authors could inject php code by choosing a malicious {block} name or {include} file name. Sites that cannot fully trust template authors should upgrade to versions 3.1.45 or 4.1.1 to receive a patch for this issue. There are currently no known workarounds. (CVE-2022-29221)

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 the stable distribution (bullseye), these problems have been fixed in version 3.1.39-2+deb11u1.
