Debian DSA-3276-1 : symfony - security update

medium Nessus Plugin ID 83919

Language:

Synopsis

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

Description

Jakub Zalas discovered that Symfony, a framework to create websites and web applications, was vulnerable to restriction bypass. It was affecting applications with ESI or SSI support enabled, that use the FragmentListener. A malicious user could call any controller via the /_fragment path by providing an invalid hash in the URL (or removing it), bypassing URL signing and security rules.

Solution

Upgrade the symfony packages.

For the stable distribution (jessie), this problem has been fixed in version 2.3.21+dfsg-4+deb8u1.
