CVE-2020-17367
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-2020-17368
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.
For the stable distribution (buster), these problems have been fixed in version 0.9.58.2-2+deb10u1.
We recommend that you upgrade your firejail packages.
For the detailed security status of firejail please refer to its security tracker page at: [link moved to references]");
