ProWeb is pleased to announce the latest release of ProWeb Easy Update. ProWeb's in-house web development team have been working to improve the features and use of this application.
ProWeb has upgraded all subscribers to the latest release.
In this Easy Update v4.8.9 release there have been a number of changes including:
For any queries feel free to contact us.
The CA/Browser Forum has implemented a change in Certification Authorities’ policy requirements, reducing the maximum lifetime for all TLS/SSL certificates to 825 days, which is just over 27 months. This is a reduction from the existing maximum term of 39 months, meaning the maximum validity for an SSL certificate is now two years, and not three.
This is an industry-wide directive which affects all certificate authorities. In accordance with the CA/Browser Forum Baseline Requirements, effective 1 March 2018, Certificate Authorities (CAs) will no longer be able to issue SSL Certificates with a validity period longer than 27-months.
As a result, ProWeb will adopt these new lifetime requirements effective 1 March 2018 and three-year certificates will be removed as available options from our website.

You may be aware of the global Kernel Memory Leakage issue relating to CPU vendors which was announced to the public yesterday by international media.
We have outlined all you need to know below and are actively working with our hardware vendors and operating system vendors to assess impact and remedial action.
We will be updating you further as information becomes available, please be assured that we are doing everything possible to remediate any potential impacts immediately.
What is the issue?
On Jan 4th, it was announced in the media (theregister.co.uk) that numerous industry wide vulnerabilities in Intel, ARM and AMD (alleged) CPU's had been identified in relationship to Kernel Memory Leakage, known as Meltdown and Spectre. These vulnerabilities impact all compute running Windows, Linux, macOS (including server OS) and operating systems will require a patch to resolve the vulnerabilities. These vulnerabilities allow for side channel exploits in rogue malicious applications to be able to read data stored on a computers system memory. It is yet unknown the impact of the operating systems patch on operating system performance, however we will continue to monitor our platforms and make the necessary adjustments where needed.
Am I affected by the vulnerability?
Yes. This is a global issue with CPU chip sets. The full extent of the impact is yet to be established and we will communicate further as more information is received. Right now, we are doing everything possible by working with our vendors to rectify and remedy the known vulnerabilities.
What could be leaked?
If your system is affected by a malicious application, an exploit could read the memory content of the host server. This may include passwords and sensitive data stored on the system.
An attacker able to execute code with user privileges, can gain access to data in memory space, thus bypassing KASLR: (kernel address space layout randomization). This is a defence mechanism used by various operating systems to place components of the kernel in randomized locations in virtual memory.
Which systems are affected?
Desktop, Laptop, and Cloud computers may be affected by Meltdown/Spectre. More technically, every Intel (and potentially ARM and AMD) processor which implements out-of-order execution is potentially affected, which is effectively every processor since 1995 (except Intel Itanium and Intel Atom before 2013).
What is the difference between Meltdown and Spectre?
Meltdown breaks the mechanism that keeps applications from accessing arbitrary system memory. Consequently, applications can access system memory. Spectre tricks other applications into accessing arbitrary locations in their memory. Both attacks use side channels to obtain the information from the accessed memory location. For a more technical discussion we refer to the papers (Meltdown and Spectre).
Is there more technical information about Meltdown and Spectre?
Yes, there is an academic paper and a blog post about Meltdown, and an academic paper about Spectre. Furthermore, there is a Google Project Zero blog entry about both vulnerabilities.
Vendors have started to classify the risk impact on their products and are slowly releasing patches remediating some of the vulnerabilities. We will be patching our cloud server environment with the recommended baseline versions for protection. Once the final fixes are made available, we will be deploying them accordingly.
If you see browser updates, we strongly recommend that you run these and as per usual, we strongly recommend checking, and applying operating system security updates as they become available.
Web Browser patches:
Firefox: https://www.mozilla.org/en-US/security/advisories/mfsa2018-01/
Google Chrome: https://www.chromium.org/Home/chromium-security/ssca
Microsoft Edge / Internet Explorer: Patches were made available Wednesday last week, but automatic updates will run from next patch cycle.
In response to the global Kernel Memory Leakage vulnerability issues that have circulated throughout the last week, we have worked closely with our hardware and operating system vendors to initiate remedial actions.
As there is no single fix to cover all the variants of Meltdown and Spectre, we are completing our patching in a phased approach, as outlined below.
Cloud Server Platform
Infrastructure Hardware
Operating System Patches
Our engineers have successfully applied all the relevant operating system patches across our Microsoft Windows servers.
Linux servers are approximately 50% done, and completion will progress during the course of the week.
Unfortunately hardware firmware updates are constantly being released and revoked due to stability issues they are presenting.
As per recommendation from Intel, its advisable to not apply their current release. We subsequently took the decision to hold back on any firmware updates until the “fixes” have matured in stability.
