Ransomware in targeted attacks

Ransomware's popularity has attracted the attention of cybercriminal gangs; they use these malicious programs in targeted attacks on large organizations in order to steal money.
In late 2016, we detected an increase in the number of attacks, the main goal of which was to launch an encryptor on an organization's network nodes and servers.

SolarEdge’s HD-Wave Inverter First Ever to Reach 99% CEC Efficiency Rating

Fremont, USA (January 31, 2017) – SolarEdge Technologies, Inc. (“SolarEdge”) (NASDAQ: SEDG), a global leader in PV inverters, power optimizers, and module-level monitoring services, announced today that its award-winning HD-Wave inverter set a new record for the California Energy Commission (CEC), by reaching 99% weighted efficiency.

Topping the CEC inverter efficiency list, SolarEdge’s HD-Wave inverter is based on a novel power conversion topology that significantly decreases inverter size and weight, while also improving efficiency. Weighing... Source: RealWire

RHEA-2017:0148-1: heketi bug fix and enhancement update

Updated heketi packages that fix several bugs and add various enhancements arenow available. Heketi provides the Red Hat Gluster Storage volume life cycle management.
Itcreates the Red Hat Gluster Storage volumes dynamically and supports multipleRed Hat Gluster Storage clusters.The following list provides the major enhancements and bug fixes made to theHeketi component for this release:* Previously, the 'endpoints' and 'service' on the 'projects/namespaces' had tobe created to use Red Hat Gluster Storage persistent volumes. With this release,when the volumes are dynamically provisioned by the gluster provisioner, thesubjected 'endpoint' and 'service' are auto created and the user will be able touse these persistent volumes. (BZ#1354640)* Previously, Heketi created a 32GB volume to store the heketi db file, whichwas much more than the average requirement. With this release, the size of thevolume is been reduced to 2GB.

This does not change the volume size of existingsetups and is applicable only for new setups. (BZ#1406649)* Previously, the minimum brick size was 4GB and the minimum volume size thatcould be created was 8GB. With this release, the minimum brick size is 1GB andvolumes as small as 1GB can be created. (BZ#1406655)* This version of Heketi adds a new cli command called 'node list' which listsall the nodes in the clusters managed by Heketi.For example:# heketi-cli node list(BZ#1351893) Before applying this update, make sure all previously released erratarelevant to your system have been applied.For details on how to apply this update, refer to:https://access.redhat.com/articles/11258Red Hat Gluster Storage Server 3.1 on RHEL-7 SRPMS: heketi-3.1.0-14.el7rhgs.src.rpm     MD5: c409e0cbff4e8612cfb3f9954347fb26SHA-256: 3aa76177f4973972cdc64cb27d84df4272c9589831ffe2124bf13949d5a2e1d7   x86_64: cns-deploy-3.1.0-14.el7rhgs.x86_64.rpm     MD5: 6e97b41c58503069f1cf631f27068bccSHA-256: 66b1f78bfbface53371ecf59931baaf5f4c22005ca7c25dcfb0bacd7e3bec32b heketi-3.1.0-14.el7rhgs.x86_64.rpm     MD5: 9dbe6ae1b6725a832f7529fcee092a2bSHA-256: d8f6497cae4f3131af89170e946d4525d88cbc5e7048b1a257e6ca6fb96a52c5 heketi-client-3.1.0-14.el7rhgs.x86_64.rpm     MD5: d0bfdf27773f60053109b2c0307d6a77SHA-256: cb8f322d49f38bf45a5441b36fe98ad36766895c01218b2e5f61c1953b46f895 python-heketi-3.1.0-14.el7rhgs.x86_64.rpm     MD5: 0a9402e3248fbb95a9562257c5b6112dSHA-256: 6fe924437ca7bf899c49a8f9b27b0a358d43d06596de2ed7ec78ddbfac5b02f0   (The unlinked packages above are only available from the Red Hat Network) 1341141 - heketi-cli: proper error message to stdout for cluster/node/device delete1341961 - heketi server doesn't log errors for node/device delete1346621 - topology info: "ID not found" error when running concurrently with volume creation.1346858 - 14 snapshots per volume in Aplo1351455 - heketi-cli should display help, when invoked1351535 - Need error logging on volume create failures1351646 - 404: heketi-cli cluster/device/node/volume info1351893 - [RFE] Add "node list" option in heketi-cli1354640 - [RFE] GlusterFS PV should not use Endpoints since they are per project1356437 - [RFE] - Volume Security Story - "permission denied" error for writes on app container1357686 - Heketi and GlusterFS deployment strategy needs to use Recreate not Rolling1370130 - Confusing error message when creating too small volume1392377 - when multiple pv claim request are made, heketi ends up creating more volumes than requested1395216 - ProvisioningFailed: Failed to provision volume with StorageClass "gold": glusterfs: create volume err: failed to get hostip Id not found1395656 - One of the node in 3 node CNS system fails to respin gluster container after reboot1397361 - Heketi distgit contains broken create_tar script.1397362 - Heketi distgit contains unneeded script1397435 - [RFE] Rebase to heketi 3.1.01397793 - Wrong "image" name mentioned in glusterfs-template.json1398578 - Update the man page1398581 - gluster-template: '/var/lib/misc/glusterfsd/' fs is not persisted after RHGS container restart1401594 - /sys/fs/cgroup is mounted as read write1406649 - Reduce the default size of "heketidbstorage" volume from 32GB to 2GB1406655 - reduce the min-vol size restriction to a lower value1410782 - strategy: type is seem as "Rolling" instead of "Recreate" while exporting the heketi dc1411227 - Prevent the RHGS docker image in a production setup from getting replaced with any new image with "latest" TAG pushed to the public Registry.1412281 - gluster pods loose /var/log mounts and fail to start.

RHSA-2016:1996-1: Important: CFME 4.1 bug fixes and enhancement update

Updated cfme packages that fix bugs and add various enhancementsare now available for Red Hat CloudForms 4.1.Red Hat Product Security has rated this update as having a security impactof Important. A Common Vulnerability Scoring System (CVSS) base score,which gives a detailed severity rating, is available for each vulnerabilityfrom the CVE link(s) in the References section. Red Hat CloudForms Management Engine delivers the insight, control,and automation needed to address the challenges of managing virtualenvironments. CloudForms Management Engine is built on Ruby on Rails,a model-view-controller (MVC) framework for web applicationdevelopment. Action Pack implements the controller and the viewcomponents.* An input validation flaw was found in the way CloudForms regularexpressions were passed to the expression engine via the JSON API and theweb-based UI. A user with the ability to view collections and filter themcould use this flaw to execute arbitrary shell commands on the host withthe privileges of the CloudForms process. (CVE-2016-7040)This issue was discovered by Tim Wade (Red Hat).Additional Changes:This update fixes bugs and adds various enhancements.Documentation for these changes is available in the Release Notes linkedto in the References section.All CFME users are advised to upgrade to these updated packages, whichcorrect these issues and add these enhancements.

RHBA-2016:1498-1: heketi update for Red Hat Gluster Storage 3.1

Details Updated heketi packages that fix several bugs and add various enhancements arenow available for Red Hat Gluster Storage 3.1. Heketi provides a RESTful management interface which can be used to manage thelife cycle of GlusterFS volumes. With Heketi, cloud services like OpenStackManila, Kubernetes, and OpenShift can dynamically provision GlusterFS volumeswith any of the supported durability types.
