NVD Description

Note: Versions mentioned in the description apply only to the upstream libjavascriptcoregtk-4_0-18 package and not the libjavascriptcoregtk-4_0-18 package as distributed by SLES. See How to fix? for SLES:15.3 relevant fixed versions and status.

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.
