Summary

xorg-server, xwayland regression

Details

USN-7299-2 fix vulnerabilities in X.Org X Server. This fix caused regression in Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. This update reverts it pending further investigation.

Original advisory details:

Jan-Niklas Sohn discovered that the X.Org X Server incorrectly handled certain memory operations. An attacker could use these issues to cause the X Server to crash, leading to a denial of service, or possibly execute arbitrary code.
