In the X.Org X server before 2017-06-19, a user authenticated to an X Session could crash or execute code in the context of the X Server by exploiting a stack overflow in the endianness conversion of X Events. En el servidor X de X.Org antes del 19-06-2017, un usuario autenticado en una Sesión X podría bloquear o ejecutar código en el contexto del servidor X al explotar un desbordamiento de pila en la conversión endianness de Eventos X. • http://www.debian.org/security/2017/dsa-3905 http://www.securityfocus.com/bid/99546 https://bugzilla.suse.com/show_bug.cgi?id=1035283 https://cgit.freedesktop.org/xorg/xserver/commit/?id=215f894965df5fb0bb45b107d84524e700d2073c https://cgit.freedesktop.org/xorg/xserver/commit/?id=8caed4df36b1f802b4992edcfd282cbeeec35d9d https://cgit.freedesktop.org/xorg/xserver/commit/?id=ba336b24052122b136486961c82deac76bbde455 • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
CVSS: 6.5EPSS: 0%CPEs: 8EXPL: 1CVE-2017-2625 – libXdmcp: weak entropy usage for session keys
https://notcve.org/view.php?id=CVE-2017-2625
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. Se ha descubierto que libXdmcp en versiones anteriores a la 1.1.2 usaba entropía débil para generar claves de sesión. En un sistema multiusuario que utilice xdmcp, un atacante local podría utilizar la información disponible en la lista de procesos para usar un ataque de fuerza bruta en la clave, permitiéndole secuestrar las sesiones de otros usuarios. It was discovered that libXdmcp used weak entropy to generate session keys. • http://www.securityfocus.com/bid/96480 http://www.securitytracker.com/id/1037919 https://access.redhat.com/errata/RHSA-2017:1865 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2625 https://cgit.freedesktop.org/xorg/lib/libXdmcp/commit/?id=0554324ec6bbc2071f5d1f8ad211a1643e29eb1f https://lists.debian.org/debian-lts-announce/2019/11/msg00024.html https://security.gentoo.org/glsa/201704-03 https://www.x41-dsec.de/lab/advisories/x41-2017-001-xorg https://access.redhat.com/security& • CWE-320: Key Management Errors CWE-331: Insufficient Entropy •

https://notcve.org/view.php?id=CVE-2017-2624
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. Se ha encontrado que xorg-x11-server en versiones anteriores a la 1.19.0 que uttilizan memcmp() para comprobar la cookie MIT recibida contra una serie de cookies válidas. Si la cookie es correcta, se puede adjuntar a la sesión de Xorg. • http://www.securityfocus.com/bid/96480 http://www.securitytracker.com/id/1037919 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-2624 https://gitlab.freedesktop.org/xorg/xserver/commit/d7ac755f0b618eb1259d93c8a16ec6e39a18627c https://lists.debian.org/debian-lts-announce/2017/11/msg00032.html https://security.gentoo.org/glsa/201704-03 https://security.gentoo.org/glsa/201710-30 https://www.x41-dsec.de/lab/advisories/x41-2017-001-xorg • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor CWE-385: Covert Timing Channel •
