CVE-2020-13753

Priority
Description
The bubblewrap sandbox of WebKitGTK and WPE WebKit, prior to 2.28.3, failed
to properly block access to CLONE_NEWUSER and the TIOCSTI ioctl.
CLONE_NEWUSER could potentially be used to confuse xdg-desktop-portal,
which allows access outside the sandbox. TIOCSTI can be used to directly
execute commands outside the sandbox by writing to the controlling
terminal's input buffer, similar to CVE-2017-5226.
Notes
jdstrandwebkit receives limited support. For details, see
https://wiki.ubuntu.com/SecurityTeam/FAQ#webkit
webkit in Ubuntu uses the JavaScriptCore (JSC) engine, not V8
