Kerentanan Improper Input Validation pada webkitgtk, wpewebkit wpe webkit +4 lainnya. Skor CVSS 3.1 10.0 (Critical) menurut NVD.

Deskripsi (NVD)

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.
