On March 29th, 2024, a backdoor was discovered in xz-utils, a suite of software that
| # Runs "$@" in a subshell with the caller's options, sets reply=(stdout stderr) | |
| # and returns the status of the executed command. Both stdout and stderr are | |
| # captured completely, including NUL bytes, incomplete UTF-8 characters and | |
| # trailing LF, if any. | |
| # | |
| # Example: | |
| # | |
| # % zsh-run-command ls -d ~ /garbage | |
| # % printf 'status: %s\nstdout: %s\nstderr: %s\n' $? "${(q+)reply[@]}" | |
| # status: 2 |
Functions that allow you to call a function not more than once in a given timeframe.
This can be illustrated with timing diagrams. In the following diagrams, f designates call to the throttled function, t is the period where the timer is running, and x shows you the actual execution point of the throttled function.
f 1 2 3 4 5 6
