MGASA-2020-0328 - Updated firejail packages fix security vulnerability

Publication date: 18 Aug 2020
URL: https://advisories.mageia.org/MGASA-2020-0328.html
Type: security
Affected Mageia releases: 7
CVE: CVE-2020-17367,
     CVE-2020-17368

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).
