CVE-2020-13753 Open this link in a new tabHow to fix?
Upgrade SLES:15.1 webkit2gtk-4_0-injected-bundles to version 2.34.3-3.92.1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream webkit2gtk-4_0-injected-bundles package and not the webkit2gtk-4_0-injected-bundles package as distributed by SLES.
See How to fix? for SLES:15.1 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.
