Linux User & Developer, Issue 166

Linux User & Developer Issue 166This month’s Linux User & Developer includes a review of the Cubietruck Plus – also known as the Cubieboard 5 – I previously reviewed in Custom PC Issue 154.

CubieTech’s latest design, the Cubietruck Plus borrows the overall design from its predecessor but swaps out the weedy dual-core Allwinner A20 processor for an altogether beefier H8 octa-core chip. Kindly supplied for review by low-power computing specialist New IT, I was eager to put the board through its paces – especially as previous octa-core single-board computer (SBC) designs have suffered from some reliability issues when fully loaded for extended periods.

Sadly, as with my earlier review, there’s one piece of information which didn’t come to light prior to the deadline: devices, including single-board computers, based on Allwinner chips and using the company’s modified Linux kernel source have been found to suffer from a back-door which allows any process running on the system to silently and immediately gain root-level (superuser) privileges. While it doesn’t allow for remote execution, it can make existing bugs more readily exploitable – and if you’re using the Cubietruck Plus or any other Allwinner-based device, it’s worth checking to see if you’re affected.

This aside, the Cubietruck Plus certainly impressed during both reviews – though if you want to find out if I think it justifies its considerable price premium over the four-core Raspberry Pi 3, you’ll have to pick up a copy of the magazine from your local newsagent, supermarket, or digitally via Zinio or similar services.
