Debian Security Advisory DSA-3276-1 firstname.lastname@example.org http://www.debian.org/security/ David Prevot May 31, 2015 http://www.debian.org/security/faq
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 unstable distribution (sid), this problem has been fixed in version 2.7.0~beta2+dfsg-2.
