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.
Notice that this fix may make Radsecproxy reject some clients that are currently (erroneously) being accepted.
For the stable distribution (squeeze), these problems have been fixed in version 1.4-1+squeeze1.
For the testing distribution (wheezy), these problems have been fixed in version 1.6.2-1.
