[PKG-Openstack-devel] Bug#783164: CVE-2015-1852: S3token incorrect condition expression for ssl_insecure.

[Thomas Goirand]

Package: python-keystoneclient
Version: 1:0.10.1-2
Severity: grave
Tags: security patch

Note from maintainer: upload fixing Sid & Jessie is comming in a few minutes.

Affects
~~~~~~~
- python-keystoneclient: versions through 1.3.0
- keystonemiddleware: versions through 1.5.0


Description
~~~~~~~~~~~
Brant Knudson from IBM reported a vulnerability in keystonemiddleware
(formerly shipped as python-keystoneclient). When the 'insecure'
option is set in a S3Token paste configuration file its value is
effectively ignored and instead assumed to be true. As a result
certificate verification will be disabled, leaving TLS connections
open to MITM attacks. Note that it's unusual to explicitly add this
option and then set it to false, so the impact of this bug is thought
to be limited. All versions of s3_token middleware with TLS settings
configured are affected by this flaw.
