    Debian-specific: no
    
    Issues were found in the handling of XML encryption in simpleSAMLphp,
    an application for federated authentication. The following two issues
    have been addressed:
    
    It may be possible to use an SP as an oracle to decrypt encrypted
    messages sent to that SP.
    
    It may be possible to use the SP as a key oracle which can be used
    to forge messages from that SP by issuing 300000-2000000 queries to
    the SP. 
    
    The oldstable distribution (lenny) does not contain simplesamlphp.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 1.6.3-2.
    
    The testing distribution (wheezy) will be fixed soon.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 1.8.2-1.
    
    We recommend that you upgrade your simplesamlphp packages.
