CVE-2020-14347 [MEDIUM] CVE-2020-14347: A flaw was found in the way xserver memory was not properly initialized A flaw was found in the way xserver memory was not properly initialized. This could leak parts of server memory to the X client. In cases where Xorg server runs with elevated privileges, this could result in possible ASLR bypass. Xorg-server before version 1.20.9 is vulnerable.

CVE-2018-14665 [MEDIUM] CVE-2018-14665: A flaw was found in xorg-x11-server before 1 A flaw was found in xorg-x11-server before 1.20.3.

CVE-2017-2624 [HIGH] CVE-2017-2624: It was found that xorg-x11-server before 1 It was found that xorg-x11-server before 1.19.0 including uses memcmp() to check the received MIT cookie against a series of valid cookies. If the cookie is correct, it is allowed to attach to the Xorg session. Since most memcmp() implementations return after an invalid byte is seen, this causes a time difference between a valid and invalid byte, which could allow an efficient brute force attack.
