Summary
Red Hat Security Advisory: python-glanceclient security update

Notes

Topic
An updated python-glanceclient package that fixes one security issue is now available for Red Hat OpenStack 3.0. The Red Hat Security Response Team has rated this update as having moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section.
Details
The python-glanceclient package provides a client for the OpenStack Glance API. It was discovered that the Python Glance client did not properly check SSL certificates. An attacker could use this flaw to conduct man-in-the-middle attacks. (CVE-2013-4111) Red Hat would like to thank the OpenStack project for reporting this issue. Upstream acknowledges Thomas Leaman of HP as the original reporter. All users of python-glanceclient are advised to upgrade to this updated package, which corrects this issue.
