Debian DSA-4262-1 : symfony - security update

critical Nessus Plugin ID 111535
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

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

Description

Multiple vulnerabilities have been found in the Symfony PHP framework which could lead to open redirects, cross-site request forgery, information disclosure, session fixation or denial of service.

Solution

Upgrade the symfony packages.

For the stable distribution (stretch), these problems have been fixed in version 2.8.7+dfsg-1.3+deb9u1.
