Summary
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.

Details
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.

Summary
Red Hat Security Advisory: Red Hat OpenStack Platform director security update
Notes
Topic
An update is now available for Red Hat OpenStack Platform 11.0 (Ocata).
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat OpenStack Platform director provides the facilities for deploying
and monitoring a private or public infrastructure-as-a-service (IaaS) cloud
based on Red Hat OpenStack Platform.
Security Fix(es):
* A resource-permission flaw was found in the python-tripleo and openstack-tripleo-heat-templates packages where ceph.client.openstack.keyring is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume.
To exploit this flaw, the attacker must have local access to an overcloud node. However by default, access to overcloud nodes is restricted and accessible only from the management undercloud server on an internal network. (CVE-2017-12155)
This issue was discovered by Katuya Kawakami (NEC).
* It was discovered that the memcached connections using UDP transport protocol can be abused for efficient traffic amplification distributed denial of service (DDoS) attacks. A remote attacker could send a malicious UDP request using a spoofed source IP address of a target system to memcached, causing it to send a significantly larger response to the target. (CVE-2018-1000115)
This update also includes the following bug fixes and enhancements:
* Prior to this update, when removing the ceph-osd RPM from overcloud nodes that do not require the package, the corresponding Ceph OSD product key was not removed. Consequently, the subscription-manager would incorrectly report that the Ceph OSD product was still installed.
With this update, the script that handles removal of the ceph-osd RPM now also removes the Ceph OSD product key. Note: The script that removes the RPM and product key executes only during the overcloud update procedure; the product key is removed only when the overcloud node is updated.
As a result, after removing the ceph-osd RPM, the subscription-manager no longer reports the Ceph OSD product is installed. (BZ#1571436)
* Previously, there were errors in the director Heat template that configures the VMAX Cinder backend driver. Consequently, the VMAX driver would not function correctly. With this update, the errors have been corrected, and the VMAX driver functions correctly. (BZ#1546799)
* This enhancement adds director support for deploying the Dell EMC VMAX cinder backend. (BZ#1546793)
* In this enhancement, if a minor update is blocked by an existing yum process that prevents the package update, the process should exit with an appropriate error message. This was added because the minor update may appear to freeze, due to yum waiting for the existing yum.pid to exit; when it eventually fails it is not immediately clear why. As a result, if there is an existing yum process preventing the package update, then the minor update fails with a clear message to indicate this: "ERROR existing yum.pid detected - can't continue! Please ensure there is no other package update process for the duration of the minor update worfklow. Exiting". (BZ#1471721)

Summary
Red Hat Security Advisory: Red Hat OpenStack Platform 8 director security and bug fix update
Notes
Topic
An update for instack-undercloud and openstack-tripleo-heat-templates is now available for Red Hat OpenStack Platform 8.0 (Liberty) director.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
memcached is a high-performance, distributed memory object caching system, generic in nature, but intended for use in speeding up dynamic web applications by alleviating database load.
instack-undercloud provides a collection of scripts and elements that can be used to install an OpenStack undercloud (using python-instack).
openstack-tripleo-heat-templates is a collection of OpenStack Orchestration templates and tools (codename heat), which can be used to help deploy OpenStack.
Security Fix(es):
* memcached: UDP server support allows spoofed traffic amplification DoS (CVE-2018-1000115)
For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.
Bug Fix(es):
* This update fixes a race condition that could cause pacemaker-managed glance-fs deployments to fail.
Now the glance-fs resource is created from a single node of the overcloud in a way that eliminates the race condition and the resultant deployment failures. (BZ#1418617)
* Prior to this update, the source IP address for cold migration and resize was determined by the default gateway configured on the source compute node.
Now the my_ip option is explicitly set to the internal_api network IP in nova.conf, ensuring the correct network is used for this traffic. (BZ#1552855)

Summary
Red Hat Security Advisory: Red Hat OpenStack Platform director security update
Notes
Topic
An update is now available for Red Hat OpenStack Platform 10.0 (Newton).
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
Red Hat OpenStack Platform director provides the facilities for deploying and monitoring a private or public infrastructure-as-a-service (IaaS) cloud based on Red Hat OpenStack Platform.
Security Fix(es):
* A resource-permission flaw was found in the python-tripleo and openstack-tripleo-heat-templates packages where ceph.client.openstack.keyring is created as world-readable. A local attacker with access to the key could read or modify data on Ceph cluster pools for OpenStack as though the attacker were the OpenStack service, thus potentially reading or modifying data in an OpenStack Block Storage volume.
To exploit this flaw, the attacker must have local access to an overcloud node. However by default, access to overcloud nodes is restricted and accessible only from the management undercloud server on an internal network. (CVE-2017-12155)
This issue was discovered by Katuya Kawakami (NEC).
* It was discovered that the memcached connections using UDP transport protocol can be abused for efficient traffic amplification distributed denial of service (DDoS) attacks. A remote attacker could send a malicious UDP request using a spoofed source IP address of a target system to memcached, causing it to send a significantly larger response to the target. (CVE-2018-1000115)
This advisory also addresses the following issues:
* This release adds support for deploying Dell EMC VMAX Block Storage backend using the Red Hat OpenStack Platform director. (BZ#1503896)
* Using composable roles for deploying Dell SC and PS Block Storage backend caused errors. The backends could only be deploying using 'cinder::config::cinder_config' hiera data.
With this update, the composable role support for deploying the Dell SC and PS Block Storage backends is updated. As a result, they can be now deployed using composable roles. (BZ#1552980)
* Previously, the iptables rules were managed by the Red Hat OpenStack Platform director and the OpenStack Networking service, which resulted in the rules created by the OpenStack Networking service to persist on to the disk. As a result, the rules that should not be loaded after an iptables restart or a system reboot would be loaded causing traffic issues.
With this update, the Red Hat OpenStack Platform director has been updated to exclude the OpenStack Networking rules from '/etc/sysconfig/iptables' when the director saves the firewall rules. As a result, iptables restart or a system reboot should work without causing traffic problems.
Note: It might be necessary to perform a rolling restart of the controller nodes to ensure that any orphaned managed neutron rules are no longer reloaded. (BZ#1541528)
* OS::TripleO::SwiftStorage::Ports* resources have been renamed to OS::TripleO::ObjectStorage::Port* to ensure standalone Object Storage nodes using the 'ObjectStorage' roles can be deployed correctly. Operators need to modify their custom templates that previously used OS::TripleO::SwiftStorage::Ports* settings. (BZ#1544802)

Details
Memcached version 1.5.5 contains an Insufficient Control of Network Message Volume (Network Amplification, CWE-406) vulnerability in the UDP support of the memcached server that can result in denial of service via network flood (traffic amplification of 1:50,000 has been reported by reliable sources). This attack appear to be exploitable via network connectivity to port 11211 UDP. This vulnerability appears to have been fixed in 1.5.6 due to the disabling of the UDP protocol by default.
