CVE-2019-10063 (retired)

Priority
Description
Flatpak before 1.0.8, 1.1.x and 1.2.x before 1.2.4, and 1.3.x before 1.3.1
allows a sandbox bypass. Flatpak versions since 0.8.1 address CVE-2017-5226
by using a seccomp filter to prevent sandboxed apps from using the TIOCSTI
ioctl, which could otherwise be used to inject commands into the
controlling terminal so that they would be executed outside the sandbox
after the sandboxed app exits. This fix was incomplete: on 64-bit
platforms, the seccomp filter could be bypassed by an ioctl request number
that has TIOCSTI in its 32 least significant bits and an arbitrary nonzero
value in its 32 most significant bits, which the Linux kernel would treat
as equivalent to TIOCSTI.
