Mulesoft ESB Runtime version 3.5.1 suffers from an authenticated privilege escalation vulnerability that can lead to remote code execution.

Red Hat Security Advisory 2014-1690-01 – The python-backports-ssl_match_hostname package provides RFC 6125 compliant wildcard matching. A denial of service flaw was found in the way Python’s SSL module implementation performed matching of certain certificate names. A remote attacker able to obtain a valid certificate that contained multiple wildcard characters could use this flaw to issue a request to validate such a certificate, resulting in excessive consumption of CPU. This issue was discovered by Florian Weimer of Red Hat Product Security.

Red Hat Security Advisory 2014-1689-01 – OpenStack Compute launches and schedules large networks of virtual machines, creating a redundant and scalable cloud computing platform. Compute provides the software, control panels, and APIs required to orchestrate a cloud, including running virtual machine instances, managing networks, and controlling access through users and projects. A race condition flaw was found in the way the nova VMware driver handled VNC port allocation. An authenticated user could use this flaw to gain unauthorized console access to instances belonging to other tenants by repeatedly spawning new instances. Note that only nova setups using the VMware driver and the VNC proxy service were affected.

Red Hat Security Advisory 2014-1691-01 – PackStack is a command-line utility that uses Puppet modules to support rapid deployment of OpenStack on existing servers over an SSH connection. PackStack is suitable for deploying both single node proof-of-concept installations and more complex multi-node installations. It was discovered that the nova.conf configuration generated by PackStack did not correctly set the libvirt_vif_driver configuration option if the Open vSwitch monolithic plug-in was not used. This could result in deployments defaulting to having the firewall disabled unless the nova configuration was manually modified after PackStack was started.

Red Hat Security Advisory 2014-1686-01 – OpenStack Networking is a pluggable, scalable, and API-driven system that provisions networking services to virtual machines. Its main function is to manage connectivity to and from virtual machines. As of Red Hat Enterprise Linux OpenStack Platform 4.0, ‘neutron’ replaces ‘quantum’ as the core component of OpenStack Networking. It was discovered that unprivileged users could in some cases reset admin-only network attributes to their default values. This could lead to unexpected behavior or in some cases result in a denial of service.

Red Hat Security Advisory 2014-1685-01 – OpenStack Image service provides discovery, registration, and delivery services for disk and server images. It provides the ability to copy or snapshot a server image, and immediately store it away. Stored images can be used as a template to get new servers up and running quickly and more consistently than installing a server operating system and individually configuring additional services. It was discovered that the image_size_cap configuration option in glance was not honored. An authenticated user could use this flaw to upload an image to glance and consume all available storage space, resulting in a denial of service.

Red Hat Security Advisory 2014-1692-01 – OpenSSL is a toolkit that implements the Secure Sockets Layer, Transport Layer Security, and Datagram Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library. This update adds support for the TLS Fallback Signaling Cipher Suite Value, which can be used to prevent protocol downgrade attacks against applications which re-connect using a lower SSL/TLS protocol version when the initial connection indicating the highest supported protocol version fails.

Red Hat Security Advisory 2014-1688-01 – The OpenStack Identity service authenticates and authorizes OpenStack users by keeping track of users and their permitted activities. The Identity service supports multiple forms of authentication, including user name and password credentials, token-based systems, and AWS-style logins. A flaw was found in the keystone V3 API. An attacker could send a single request with the same authentication method multiple times, possibly leading to a denial of service due to generating excessive load with minimal requests. Only keystone setups with the V3 API enabled were affected by this issue.
