There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - An issue was discovered in Symfony 2.7.x before 2.7.38, 2.8.x before 2.8.31, 3.2.x before 3.2.14, and
    3.3.x before 3.3.13. DefaultAuthenticationSuccessHandler or DefaultAuthenticationFailureHandler takes the
    content of the _target_path parameter and generates a redirect response, but no check is performed on the
    path, which could be an absolute URL to an external domain. This Open redirect vulnerability can be
    exploited for example to mount effective phishing attacks. (CVE-2017-16652)

Several security vulnerabilities have been discovered in symfony, a PHP web application framework. Numerous symfony components are affected: Security, bundle readers, session handling, SecurityBundle, HttpFoundation, Form, and Security\Http.

For Debian 8 'Jessie', these problems have been fixed in version 2.3.21+dfsg-4+deb8u4.

We recommend that you upgrade your symfony packages.

Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - An issue was discovered in Symfony 2.7.x before 2.7.38, 2.8.x before 2.8.31, 3.2.x before 3.2.14, and     3.3.x before 3.3.13. DefaultAuthenticationSuccessHandler or DefaultAuthenticationFailureHandler takes the     content of the _target_path parameter and generates a redirect response, but no check is performed on the     path, which could be an absolute URL to an external domain. This Open redirect vulnerability can be     exploited for example to mount effective phishing attacks. (CVE-2017-16652)

Note that Nessus relies on the presence of the package as reported by the vendor.
