Mageia 2020-0328: firejail security update
Summary
It was reported that firejail does not respect the end-of-options separator
("--"), allowing an attacker with control over the command line options of the
sandboxed application, to write data to a specified file (CVE-2020-17367).
It was reported that firejail when redirecting output via --output or
--output-stderr, concatenates all command line arguments into a single string
that is passed to a shell. An attacker who has control over the command line
arguments of the sandboxed application could take advantage of this flaw to run
arbitrary commands (CVE-2020-17368).
