This is the official release announcement for IPFire 2.15 – Core Update 84. This is a release that fixes some security issues in the GNU bash package which are commonly known as “Shellshock” and comes with more fixes and minor feature enhancements.
As you may have already seen on the news, the Shellshock issues made more people look into the code of the default shell of many *nix systems. Those people found many more programming errors and provided fixes for them which have been applied in this release. IPFire is now shipping GNU bash 4.3.30 and the companion library
readline in version 6.3.
There have been some Denial-of-Service issues in the
squid web proxy which have been fixed in release 3.4.8. Those are of minor severity only and quite possibly cannot be exploited to inject code.
The firewall got a couple of new features which I explained in detail in a post on the IPFire planet. Both enhance the firewall to better protect hosted services from Denial-of-Service attacks and similar things by limiting the number of new connections that can be opened within a certain span of time or by limiting the overall number of open connections by a host on the Internet.
Using NAT for rules where the source and destination is in the same subnet is now possible. Some code has been cleaned up and made more robust. The
firewall.local script will now also be reloaded when settings of the firewall are changed on the web user interface.
The P2P block feature of the firewall has not been very effective for many protocols. The detection has now been improved and blocking unwanted P2P protocols from your network works now much better but will result in a bit more load.
dnsmasq, the DNS proxy working inside of IPFire, has been updated to version 2.72 which includes some stability fixes and fixes some of the crashes some IPFire users have been experiencing especially in conjunction with (faulty) DNSSEC-enabled DNS recursors on the Internet.
partedhas been updated to version 3.1.
