Upgrade Debian:10
webkit2gtk
to version 2.28.3-2~deb10u1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream webkit2gtk
package and not the webkit2gtk
package as distributed by Debian
.
See How to fix?
for Debian:10
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.
