Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process. Quick emulator (QEMU) en versiones anteriores a la 2.8 construido con el soporte del emulador Cirrus CLGD 54xx VGA Emulator es vulnerable a un problema de acceso fuera de límites. El problema puede ocurrir al copiar datos VGA en cirrus_bitblt_cputovideo. • http://rhn.redhat.com/errata/RHSA-2017-0328.html http://rhn.redhat.com/errata/RHSA-2017-0329.html http://rhn.redhat.com/errata/RHSA-2017-0330.html http://rhn.redhat.com/errata/RHSA-2017-0331.html http://rhn.redhat.com/errata/RHSA-2017-0332.html http://rhn.redhat.com/errata/RHSA-2017-0333.html http://rhn.redhat.com/errata/RHSA-2017-0334.html http://rhn.redhat.com/errata/RHSA-2017-0350.html http://rhn.redhat.com/errata/RHSA-2017-0351.html http://rhn • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host. Quick emulator (QEMU) con soporte integrado para el emulador Cirrus CLGD 54xx VGA es vulnerable a un problema de acceso fuera de límites. Podría ocurrir mientras se copian datos VGA mediante la copia bitblt en modo backward. • http://rhn.redhat.com/errata/RHSA-2017-0309.html http://rhn.redhat.com/errata/RHSA-2017-0328.html http://rhn.redhat.com/errata/RHSA-2017-0329.html http://rhn.redhat.com/errata/RHSA-2017-0330.html http://rhn.redhat.com/errata/RHSA-2017-0331.html http://rhn.redhat.com/errata/RHSA-2017-0332.html http://rhn.redhat.com/errata/RHSA-2017-0333.html http://rhn.redhat.com/errata/RHSA-2017-0334.html http://rhn.redhat.com/errata/RHSA-2017-0344.html http://rhn • CWE-125: Out-of-bounds Read CWE-787: Out-of-bounds Write •

Citrix NetScaler ADC and NetScaler Gateway 10.5 before Build 65.11, 11.0 before Build 69.12/69.123, and 11.1 before Build 51.21 randomly generates GCM nonces, which makes it marginally easier for remote attackers to obtain the GCM authentication key and spoof data by leveraging a reused nonce in a session and a "forbidden attack," a similar issue to CVE-2016-0270. Citrix NetScaler ADC y NetScaler Gateway 10.5 en versiones anteriores a Build 65.11, 11.0 en versiones anteriores a Build 69.12/69.123 y 11.1 en versiones anteriores a Build 51.21 genera aleatoriamente GCM nonces, lo que hace marginalmente más fácil a atacantes remotos obtener la clave de autenticación de GCM y falsificar datos aprovechando aprovechando una nonce reutilizada en una sesión y un "ataque prohibido", un problema similar a CVE-2016-0270. • http://www.securityfocus.com/bid/96151 https://github.com/nonce-disrespect/nonce-disrespect https://support.citrix.com/article/CTX220329 • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
