Security: CopperheadOS, remctl, and Open Source Security Podcast
-
Further securing devices running CopperheadOS by using separate Encryption/Lockscreen passphrases
If you value “vendor-based” security more than freedom, you may consider CopperheadOS an viable alternative to the free but rather insecure Replicant (it requires an unlocked bootloader and is way behind in terms of security patches atm). Personally, I find both neither Replicant nor CopperheadOS perfectly satisfying options, but they are the very best you can have at the moment. In the future, I hope that (1) more devices will be supported by non-Android-based alternatives like postmarketOS and (2) devices which require less blobs such as the Librem 5 (I highly doubt that it will run completely without blobs) will become available.

remctl 3.14
remctl is a client/server protocol supporting remote execution of specific configured commands using GSS-API or ssh for authentication and encryption.
This is a minimal release that fixes a security bug introduced in 3.12, discovered by Santosh Ananthakrishnan. A remctl client with the ability to run a server command with the sudo configuration option may be able to corrupt the configuration of remctld to run arbitrary commands, although I believe this would be moderately difficult to do. Only remctld (not remctl-shel) is vulnerable, and only if there are commands using the sudo configuration option.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
