    Package        : radsecproxy
    Vulnerability  : SSL certificate verification weakness
    Problem type   : remote
    Debian-specific: no
    CVE ID         : CVE-2012-4523 CVE-2012-4566
    
    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.
    
    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.
    
    For the unstable distribution (sid), these problems have been fixed in
    version 1.6.2-1.
    
    We recommend that you upgrade your radsecproxy packages.
