Debian LTS Advisory DLA-2336-1 [email protected]

Package : firejail
Version : 0.9.44.8-2+deb9u1
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 Debian 9 stretch, these problems have been fixed in version
0.9.44.8-2+deb9u1.
We recommend that you upgrade your firejail packages.
