critical Nessus Plugin ID 172497

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 ESM / 20.04 ESM / 22.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5947-1 advisory.

 Fabien Potencier discovered that Twig was not properly enforcing sandbox policies when dealing with objects automatically cast to strings by PHP. An attacker could possibly use this issue to expose sensitive information. This issue was only fixed in Ubuntu 16.04 ESM and Ubuntu 18.04 ESM. (CVE-2019-9942)

 Marlon Starkloff discovered that Twig was not properly enforcing closure constraints in some of its array filtering functions. An attacker could possibly use this issue to execute arbitrary code. This issue was only fixed in Ubuntu 20.04 ESM. (CVE-2022-23614)

 Dariusz Tytko discovered that Twig was not properly verifying input data utilized when defining pathnames used to access files in a system. An attacker could possibly use this issue to access unauthorized resources and expose sensitive information. (CVE-2022-39261)

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

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