CVE-2017-2625 (GCVE-0-2017-2625)

Vulnerability from cvelistv5 – Published: 2018-07-27 18:00 – Updated: 2024-08-05 14:02

Summary

It was discovered that libXdmcp before 1.1.2 including used weak entropy to generate session keys. On a multi-user system using xdmcp, a local attacker could potentially use information available from the process list to brute force the key, allowing them to hijack other users' sessions.

Severity

6.5 (Medium)

CVE-2017-2624 (GCVE-0-2017-2624)

Vulnerability from cvelistv5 – Published: 2018-07-27 18:00 – Updated: 2024-08-05 14:02

Summary

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.

Severity

5.9 (Medium)
