Episode 188

This week the common theme is vulnerabilities in setuid-root
binaries and their use of environment variables, so we take a look
at a great blog post from the Trail of Bits team about one such
example in the venerable `chfn` plus we look at some security
vulnerabilities in, and updates for the Linux kernel, Go Text, the
X Server and more, and finally we cover the recent announcement of
Ubuntu 22.04.2 LTS.
