Debian Security Advisory DSA-4742-1 [email protected]

Package : firejail
CVE ID : CVE-2020-17367 CVE-2020-17368
Tim Starling discovered two vulnerabilities in firejail, a sandbox
program to restrict the running environment of untrusted applications.
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 run arbitrary other 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.
