"The remote NewStart CGSL host, running version CORE 5.05 / MAIN 5.05, has flatpak packages installed that are affected
by a vulnerability:
- 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. (CVE-2019-10063)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
