CVE-2018-7750 – Paramiko 2.4.1 - Authentication Bypass
https://notcve.org/view.php?id=CVE-2018-7750
transport.py in the SSH server implementation of Paramiko before 1.17.6, 1.18.x before 1.18.5, 2.0.x before 2.0.8, 2.1.x before 2.1.5, 2.2.x before 2.2.3, 2.3.x before 2.3.2, and 2.4.x before 2.4.1 does not properly check whether authentication is completed before processing other requests, as demonstrated by channel-open. A customized SSH client can simply skip the authentication step. transport.py en la implementación del servidor SSH de Paramiko, en versiones anteriores a la 1.17.6; versiones 1.18.x anteriores a la 1.18.5; versiones 2.0.x anteriores a la 2.0.8; versiones 2.1.x anteriores a la 2.1.5; versiones 2.2.x anteriores a la 2.2.3; versiones 2.3.x anteriores a la 2.3.2 y versiones 2.4.x anteriores a la 2.4.1, no comprueba adecuadamente si la autenticación se ha completado antes de procesar otras peticiones, tal y como demuestra channel-open. Un cliente SSH personalizado puede simplemente omitir el paso de autenticación. It was found that when acting as an SSH server, paramiko did not properly check whether authentication is completed before processing other requests. A customized SSH client could use this to bypass authentication when accessing any resources controlled by paramiko. • https://www.exploit-db.com/exploits/45712 https://github.com/jm33-m0/CVE-2018-7750 http://www.securityfocus.com/bid/103713 https://access.redhat.com/errata/RHSA-2018:0591 https://access.redhat.com/errata/RHSA-2018:0646 https://access.redhat.com/errata/RHSA-2018:1124 https://access.redhat.com/errata/RHSA-2018:1125 https://access.redhat.com/errata/RHSA-2018:1213 https://access.redhat.com/errata/RHSA-2018:1274 https://access.redhat.com/errata/RHSA-2018:1328 https: • CWE-287: Improper Authentication •
CVE-2018-1050 – samba: NULL pointer dereference in printer server process
https://notcve.org/view.php?id=CVE-2018-1050
All versions of Samba from 4.0.0 onwards are vulnerable to a denial of service attack when the RPC spoolss service is configured to be run as an external daemon. Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash. Todas las versiones de Samba, desde la 4.0.0 en adelante, son vulnerables a un ataque de denegación de servicio (DoS) cuando el servicio RPC spoolss se configura para ejecutarse como demonio externo. La falta de comprobaciones de saneamiento de entradas en algunos de los parámetros de entrada en las llamadas RPC spoolss podrían provocar que el servicio print spooler se cierre inesperadamente. A null pointer dereference flaw was found in Samba RPC external printer service. • http://www.securityfocus.com/bid/103387 http://www.securitytracker.com/id/1040493 https://access.redhat.com/errata/RHSA-2018:1860 https://access.redhat.com/errata/RHSA-2018:1883 https://access.redhat.com/errata/RHSA-2018:2612 https://access.redhat.com/errata/RHSA-2018:2613 https://access.redhat.com/errata/RHSA-2018:3056 https://bugzilla.redhat.com/show_bug.cgi?id=1538771 https://help.ecostruxureit.com/display/public/UADCE725/Security+fixes+in+StruxureWare+Data+Center+Expert+v7.6. • CWE-476: NULL Pointer Dereference •

https://notcve.org/view.php?id=CVE-2018-6070
Lack of CSP enforcement on WebUI pages in Bink in Google Chrome prior to 65.0.3325.146 allowed an attacker who convinced a user to install a malicious extension to bypass content security policy via a crafted Chrome Extension.
