Ralf Paffrath reported that Radsecproxy, a RADIUS protocol proxy, mixed up pre- and post-handshake verification of clients. This vulnerability may wrongly accept clients without checking their certificate chain under certain configurations.
Raphael Geissert spotted that the fix for CVE-2012-4523 was incomplete, giving origin to CVE-2012-4566. Both vulnerabilities are fixed with this update.
Notice that this fix may make Radsecproxy reject some clients that are currently (erroneously) being accepted.
