Debian DLA-3147-1 : twig - LTS security update

high Nessus Plugin ID 166040

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

The remote Debian 10 host has packages installed that are affected by a vulnerability as referenced in the dla-3147 advisory.

- Twig is a template language for PHP. Versions 1.x prior to 1.44.7, 2.x prior to 2.15.3, and 3.x prior to 3.4.3 encounter an issue when the filesystem loader loads templates for which the name is a user input. It is possible to use the `source` or `include` statement to read arbitrary files from outside the templates' directory when using a namespace like `@somewhere/../some.file`. In such a case, validation is bypassed.
Versions 1.44.7, 2.15.3, and 3.4.3 contain a fix for validation of such template names. There are no known workarounds aside from upgrading. (CVE-2022-39261)

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

Solution

Upgrade the twig packages.

For Debian 10 Buster, this problem has been fixed in version 2.6.2-2+deb10u1.
