We have rebuilt all of the tarballs and images for our supported distributions to include in-kernel fixes for the SACK Panic vulnerability disclosed by Netflix last month. For an in-depth discussion of SACK Panic, see this RedHat Security Advisory.
In the process we made two version upgrades:
- The Alpine Linux netboot installer was updated to version 3.10.0.
- The Arch Linux netboot installer was updated to version 2019.07.01, and the installable tarball was rebuilt.
Our distribution images and netboot installers are available from the management console of any Prgmr.com VPS.
