This is the official release announcement for IPFire 2.19 – Core Update 101. This update contains various security fixes and bug fixes. These are the changes in detail:
Yann Cam, an independent security researcher, discovered to vulnerabilities in the IPFire Web User interface that could be used in some circumstances. In the
ipinfo.cgi file, a cross-site scripting attack could be executed on logged in users and in two more CGI files (
chpasswd.cgi), a remote code execution vulnerability was found which allowed attackers to use the aforementioned cross-site scripting attack to execute shell commands as an unprivileged user on the IPFire system.
These attacks are only possible to perform on an admin’s computer and only in that instance when the administrator is logged in to the web user interface. Of course we recommend to install this update as soon as possible to close these vulnerabilities.
We would like to thank Yann to look closely at the IPFire code and help us to improve it and we would like to invite everyone who wants to do so as well and report any bugs or security vulnerabilities that they may find.
The web proxy
squid was patched against a vulnerability filed under CVE-2016-3947 that cannot be exploited in IPFire.
On many systems, some protocols that require special care by the connection tracking implementation failed to traverse NAT. These include FTP, SIP and PPTP and where unfortunately not discovered in the testing phase of Core Update 100 before.
Those connection tracking helpers are now enabled by default on all migrated systems.
dmidecodewas added on x86. A tool to read information from the BIOS.
We are currently crowdfunding a Captive Portal for IPFire and would like you to ask to check it out and support us!
