Firejail before 0.9.60 allows truncation (resizing to length 0) of the
firejail binary on the host by running exploit code inside a firejail
sandbox and having the sandbox terminated. To succeed, certain conditions
need to be fulfilled: The jail (with the exploit code inside) needs to be
started as root, and it also needs to be terminated as root from the host
(either by stopping it ungracefully (e.g., SIGKILL), or by using the
 --shutdown control command) (CVE-2019-12499).

In Firejail before 0.9.60, seccomp filters are writable inside the jail,
leading to a lack of intended seccomp restrictions for a process that is
joined to the jail after a filter has been modified by an attacker
(CVE-2019-12589).");
