Summary

Multiple security issues have been found in Iceweasel, Debian's version of the Mozilla Firefox web browser: Multiple memory safety errors, missing input sanitising vulnerabilities, use-after-free vulnerabilities, buffer overflows and other programming errors may lead to the execution of arbitrary code, privilege escalation, information leaks or cross-site-scripting. We're changing the approach for security updates for Iceweasel, Icedove and Iceape in stable-security: Instead of backporting security fixes, we now provide releases based on the Extended Support Release branch. As such, this update introduces packages based on Firefox 17 and at some point in the future we will switch to the next ESR branch once ESR 17 has reached it's end of life. Some Xul extensions currently packaged in the Debian archive are not compatible with the new browser engine. A solution to keep packaged extensions compatible with the Mozilla releases is still being sorted out. We don't have the resources to backport security fixes to the Iceweasel release in oldstable-security any longer. If you're up to the task and want to help, please get in touch with team@security.debian.org. Otherwise, we'll announce the end of security support for Iceweasel, Icedove and Iceape in Squeeze in the next update round.
