  • Improved error message formatting overall.
  • Program now gracefully handles bad or offline repositories.
  • Secure repositories can now be disabled/enabled in Repository Manager.

Arca Noae Package Manager is available in English with Spanish, French, Italian, German, Dutch, and Swedish language packs. Some have added help file translations in this version.

Updated Uniaud Driver Package Released

Arca Noae is pleased to announce the immediate availability of an updated Uniaud Audio Driver Package for ArcaOS, OS/2, and eComStation. (Uniaud-20180117)

This is a minor maintenance release that contains some fixes for Realtek mixer devices.

This release of Uniaud32 also implements MSI support. MSI only works with the ACPI PSD version 3.23.04 or higher. It is not required to use the ACPI PSD with Uniaud. If you don’t use ACPI then Uniaud will just use normal interrupts. If you are using the ACPI PSD, it must be version 3.23.04 or higher or your system may trap. If you are using an earlier version of ACPI, upgrade ACPI first before installing this version of Uniaud.

More information about the Uniaud Package may be found in the Uniaud wiki.

If you have ArcaOS, this driver package is available for download from the Arca Noae website as part of the Support & Maintenance subscription for your ArcaOS product. Please log into your account and see your ArcaOS order details page to access your software.

If you have an Arca Noae OS/2 & eCS Drivers and Software Subscription, this driver package is available for download from the Arca Noae website as part of your Arca Noae OS/2 & eCS Drivers and Software Subscription. Please log into your account in order to access your software.

If you are still running OS/2 and/or eComStation systems and haven’t yet purchased a software subscription, this is a great reason to do so now. It may also be a good time to consider moving up to ArcaOS.

Policy statement concerning Spectre and Meltdown exploits

Spectre and Meltdown are terms used to describe two potential exploits in a class of security attacks commonly termed “timing attacks” because they access data which may be sensitive in nature (passwords and other information) from areas of memory which may only be available at specific times (either moved elsewhere or removed entirely at other times). They belong to the more general class termed “side-channel attacks,” because they exploit the hardware itself, rather than breaking encryption or utilizing a software flaw. For more technical information regarding these exploits, please refer to the links section, below.

Arca Noae engineers are monitoring the situation, and while there is still much contradictory information crossing the internet at this time, we believe we have been able to assess at least some of the risk and provide some guidance to users of the OS/2 platform (OS/2 Warp, eComStation, and ArcaOS). As further reliable information becomes available, this post will be updated to reflect any change in Arca Noae’s position and any actions we may plan to take.

General information

In order to gain access to any information in privileged memory using one of these exploits, a user-level application must be launched on the specific machine to be compromised. This means that presently, an OS/2 executable must be used as the attack vector. As of this writing, we are not aware of any such code which executes on the OS/2 platform.

Browser-based attacks (running JavaScript) appear to require greater precision in a high-resolution timer than is currently available on OS/2, making such exploits more difficult than on other platforms, if not altogether impossible. It should also be noted that any such JavaScript-based attack would have to also be specifically designed to handle access to memory regions as managed by OS/2 (in other words, a malicious JavaScript program must be written for OS/2 and specifically to run in the OS/2 browser version in which it is running; a JavaScript program written for Windows or Linux will not work on OS/2). Realistically, the chance of this level of coding detail is extremely small.

Risks – virtual installations vs bare metal

By far, virtualized environments (running OS/2 as a guest under some other more vulnerable platform) are at the greatest risk, because the host system may rightly have access to the guest’s memory and virtualized processor. A host running a vulnerable operating system with an exploitable CPU which remains unpatched is the greatest concern. Arca Noae believes bare metal installations of OS/2-based operating systems are at much less risk.

Arca Noae’s current strategy

To date, we have not identified a need for a kernel patch to mitigate the risk of any hypothetical Spectre or Meltdown attack against OS/2-based systems. We continue to monitor the available information and will adjust our strategy as conditions require.

Arca Noae’s current recommendations

For virtualized and bare metal installations, Arca Noae recommends only running software obtained from trusted sources. Per stand practice, reasonable security precautions should be taken when accessing the internet, particularly when visiting unfamiliar or untrusted sites, and browser cache should be cleared regularly. The use of a NAT firewall is also encouraged (either a separate one, as built into a broadband router or at a minimum, a software firewall running on the local OS/2 system, such as InJoy Firewall).

Because a malicious application designed to utilize one of these exploits would have to be downloaded or copied to the target OS/2 system and then executed locally, normal malware protections remain the best first line of defense.

For virtualized installations, Arca Noae recommends applying to the host system whatever patches are made available and recommended by the developer of the host operating system.
