Summary
xorg-server, xorg-server-hwe-16.04, xorg-server-lts-xenial vulnerabilities
Details

It was discovered that the X.Org X server incorrectly handled endianness conversion of certain X events. An attacker able to connect to an X server, either locally or remotely, could use this issue to crash the server, or possibly execute arbitrary code as an administrator. (CVE-2017-10971)

It was discovered that the X.Org X server incorrectly handled endianness conversion of certain X events. An attacker able to connect to an X server, either locally or remotely, could use this issue to possibly obtain sensitive information. (CVE-2017-10972)

Eric Sesterhenn discovered that the X.Org X server incorrectly compared MIT cookies. An attacker could possibly use this issue to perform a timing attack and recover the MIT cookie. (CVE-2017-2624)
