    Package        : symfony
    CVE ID         : CVE-2015-4050
    
    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.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 2.3.21+dfsg-4+deb8u1.
    
    For the testing distribution (stretch), this problem has been fixed
    in version 2.7.0~beta2+dfsg-2.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.7.0~beta2+dfsg-2.
    
    We recommend that you upgrade your symfony packages.
