Heap-based buffer overflow in Sudo
At this point, can somebody recommend linux security best practices on desktop? I already have two user accounts one for important stuff and other for unimportant stuff. I prefer to use sandboxed apps, but flatpaks don't look well maintained compared to official repositories, and often unofficial. Firejail seems quite controversial due to use of UserNS? What do veterans in security recommend for sandboxing of user apps?
