CVE-2017-2624 2Debian X.org 2Debian Linux X Server Aug 29, 2025 Jul 27, 2018 N/A· v4 7.0 HIGH· v3 1.9 LOW· v2 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.Show less
