Debian DLA-1298-1 : simplesamlphp security update

critical Nessus Plugin ID 107133

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities have been discovered in SimpleSAMLphp, a framework for authentication, primarily via the SAML protocol.

CVE-2016-9814 & CVE-2016-9955

An incorrect check of return values in the signature validation utilities allowed an attacker to get invalid signatures accepted as valid in the rare case of an error occurring during validation.

SSPSA-201802-01 (no CVE yet)

Critical signature validation vulnerability.

In addition this update adds a patch to solve excessive resource consumption in case of SimpleSAMLphp processing a large metadata file.

For Debian 7 'Wheezy', these problems have been fixed in version 1.9.2-1+deb7u3.

We recommend that you upgrade your simplesamlphp packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected simplesamlphp package.
