Debian DSA-2330-1 : simplesamlphp - XML encryption weakness

high Nessus Plugin ID 56663

Language:

Synopsis

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

Description

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.

Solution

Upgrade the simplesamlphp packages.

For the stable distribution (squeeze), this problem has been fixed in version 1.6.3-2.
