Descriptions

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.

CLONE_NEWUSER podría ser usada potencialmente para confundir xdg-desktop-portal, que permite el acceso fuera del sandbox. TIOCSTI puede ser usado para ejecutar comandos directamente fuera del sandbox al escribir en el búfer de entrada del terminal de control, similar a CVE-2017-5226
