A NULL pointer dereference exists in curl 7.21.0 to and including curl 7.58.0 in the LDAP code that allows an attacker to cause a denial of service Existe una desreferencia de puntero NULL en curl, de la versión 7.21.0 a la 7.58.0, en el código LDAP que permite que un atacante provoque una denegación de servicio (DoS). A NULL pointer dereference flaw was found in the way libcurl checks values returned by the openldap ldap_get_attribute_ber() function. A malicious LDAP server could use this flaw to crash a libcurl client application via a specially crafted LDAP reply. • http://www.oracle.com/technetwork/security-advisory/cpujul2018-4258247.html http://www.oracle.com/technetwork/security-advisory/cpuoct2018-4428296.html http://www.securityfocus.com/bid/103415 http://www.securitytracker.com/id/1040529 https://access.redhat.com/errata/RHBA-2019:0327 https://access.redhat.com/errata/RHSA-2018:3157 https://access.redhat.com/errata/RHSA-2018:3558 https://access.redhat.com/errata/RHSA-2020:0544 https://access.redhat.com/errata/RHSA-2020:0594 https://curl&# • CWE-476: NULL Pointer Dereference •

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.

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 •

Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display. Quick Emulator (también conocido como QEMU), cuando se integra con soporte para Cirrus CLGD 54xx VGA Emulator, permite que usuarios privilegiados locales, invitados del sistema operativo, provoquen una denegación de servicio (acceso fuera de límites y cierre inesperado del proceso QEMU) aprovechando los cálculos de región incorrectos al actualizar la pantalla VGA. • http://lists.opensuse.org/opensuse-security-announce/2019-03/msg00042.html http://www.openwall.com/lists/oss-security/2018/03/09/1 http://www.securityfocus.com/bid/103350 https://access.redhat.com/errata/RHSA-2018:1369 https://access.redhat.com/errata/RHSA-2018:1416 https://access.redhat.com/errata/RHSA-2018:2162 https://bugzilla.redhat.com/show_bug.cgi?id=1553402 https://lists.nongnu.org/archive/html/qemu-devel/2018-03/msg02174.html https://usn.ubuntu.com/3649-1 ht • CWE-125: Out-of-bounds Read •
