Release Notes

This is the official release announcement for IPFire 2.17 – Core Update 92. This update comes with various security fixes for the OpenSSL library and the squid web proxy server.

Security Fixes

openssl 1.0.2d

The openssl package has been updated to version 1.0.2d because of a high severity security fix filed under CVE-2015-1793.

During certificate verification, OpenSSL (starting from version 1.0.1n and
1.0.2b) will attempt to find an alternative certificate chain if the first
attempt to build such a chain fails. An error in the implementation of this
logic can mean that an attacker could cause certain checks on untrusted
certificates to be bypassed, such as the CA flag, enabling them to use a valid
leaf certificate to act as a CA and "issue" an invalid certificate.

More information can be found in the security advisory.
