This is the official release announcement for IPFire 2.17 – Core Update 91. This update comes with various security fixes – most notably fixes for six security vulnerabilities in the OpenSSL library and two more vulnerabilities in strongSwan.

OpenSSL security vulnerabilities

There are six security vulnerabilities that are fixed in version 1.0.2b of openssl. This version contained an ABI breakage bug that required us to wait for a fix for that and rebuild this Core Update.

Among these are fixes for the Logjam vulnerability and others that are filed under CVE-2015-1788, CVE-2015-1789, CVE-2015-1790, CVE-2015-1792, CVE-2015-1791, and CVE-2014-8176.

StrongSwan IPsec security vulnerability

In strongSwan 5.3.1, a security vulnerability that is filed under CVE-2015-3991 was fixed. A denial-of-service and potential code execution was possible with specially crafted IKE messages.

IPFire ships now version 5.3.2 which fixes an second vulnerability (CVE-2015-4171).

Other package updates

A number of other packages have been updated: libnet 1.16, libxml2 2.9.2, libxslt 1.1.28, newt 0.52.19, slang 2.3.0, pcre 8.37

Minor changes

  • The P2P block feature is now disabled by default on new installations. There are many false-positive cases and the usage of P2P networks has declined in the past so that we do not consider this a good default setting any longer. Existing installations remain unchanged.
  • DHCP Server: The list of static leases is now searchable. Static leases created from the list of dynamic leases are now added and the user menu will allow editing the new entry right away.

We strongly recommend to install this update as soon as possible and reboot the system afterwards.
