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

high Nessus Plugin ID 160680

Language:

Synopsis

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

Description

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

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. For the detailed security status of smarty3 please refer to its security tracker page at: https://security- tracker.debian.org/tracker/smarty3 Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS

Tenable has extracted the preceding description block directly from the Debian security advisory.

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.
