Debian DLA-2119-1 : python-pysaml2 security update

high Nessus Plugin ID 134092

Language:

Synopsis

The remote Debian host is missing a security update.

Description

It was discovered that pysaml2, a Python implementation of SAML to be used in a WSGI environment, was susceptible to XML signature wrapping attacks, which could result in a bypass of signature verification.

For Debian 8 'Jessie', this problem has been fixed in version 2.0.0-1+deb8u3.

We recommend that you upgrade your python-pysaml2 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 python-pysaml2, and python-pysaml2-doc packages.
