[Bglug] new Linux vulnerability

[Brad Rodriguez]

Seems to require local access, so not an emergency for many of us, but
make sure your distro is up to date nevertheless:

A bug lurking for 12 years gives attackers root on most major Linux
distros

"Linux users on Tuesday got a major dose of bad news—a 12-year-old
vulnerability in a system tool called Polkit gives attackers unfettered
root privileges on machines running most major distributions of the open
source operating system.

Previously called PolicyKit, Polkit manages system-wide privileges in
Unix-like OSes. It provides a mechanism for nonprivileged processes to
safely interact with privileged processes. It also allows users to
execute commands with high privileges by using a component called
pkexec, followed by the command."
