X.Org X11 X server. Security Fix(es): A flaw was found in X.Org Server Overlay Window. A Use-After-Free may lead to local privilege escalation. If a client explicitly destroys the compositor overlay window (aka COW), the Xserver would leave a dangling pointer to that window in the CompScreen structure, which will trigger a use-after-free later.(CVE-2023-1393) An update for xorg-x11-server is now available for openEuler-20.03-LTS-SP1,openEuler-20.03-LTS-SP3,openEuler-22.03-LTS and openEuler-22.03-LTS-SP1. openEuler Security has rated this update as having a security impact of high.
