Debian DSA-2573-1 : radsecproxy - SSL certificate verification weakness

medium Nessus Plugin ID 62872

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the radsecproxy packages.

For the stable distribution (squeeze), these problems have been fixed in version 1.4-1+squeeze1.
