Debian Security Advisory DSA-2330-1 security@debian.org http://www.debian.org/security/ Thijs Kinkhorst October 27, 2011 http://www.debian.org/security/faq


Package : simplesamlphp Vulnerability : xml encryption weakness Problem type : remote 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.
