Chris Buechler has announced the release of pfSense 2.2.1, a security and bug-fix update of the project's FreeBSD-based specialist operating system for firewalls and routers: "pfSense software 2.2.1 release is now available, bringing a number of bug fixes and some security fixes. Security fixes: pfSense-SA-15_02.igmp - integer overflow in IGMP protocol; pfSense-SA-15_03.webgui - multiple XSS vulnerabilities in the pfSense WebGUI; pfSense-SA-15_04.webgui - arbitrary file deletion vulnerability in the pfSense WebGUI; FreeBSD-EN-15:01.vt - vt(4) crash with improper ioctl parameters; FreeBSD-EN-15:02.openssl - update to include reliability fixes from OpenSSL. A note on the OpenSSL 'FREAK' vulnerability: does not affect the web server configuration on the firewall as it does not have export ciphers enabled. pfSense 2.2 already included OpenSSL 1.0.1k which addressed the client-side vulnerability. If packages include a web server or similar component, such as a proxy, an improper user configuration may be affected. Consult the package documentation or forum for details."
