https://notcve.org/view.php?id=CVE-2017-15119
The Network Block Device (NBD) server in Quick Emulator (QEMU) before 2.11 is vulnerable to a denial of service issue. It could occur if a client sent large option requests, making the server waste CPU time on reading up to 4GB per request. A client could use this flaw to keep the NBD server from serving other requests, resulting in DoS. El servidor Network Block Device (NBD) en Quick Emulator (QEMU) en versiones anteriores a la 2.11 es vulnerable a un problema de denegación de servicio (DoS). Esto puede ocurrir si un cliente envía grandes peticiones de opciones, haciendo que el servidor pierda tiempo de CPU al leer hasta 4GB por petición. • http://www.openwall.com/lists/oss-security/2017/11/28/9 http://www.securityfocus.com/bid/102011 https://access.redhat.com/errata/RHSA-2018:1104 https://access.redhat.com/errata/RHSA-2018:1113 https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2017-15119 https://lists.gnu.org/archive/html/qemu-devel/2017-11/msg05044.html https://usn.ubuntu.com/3575-1 https://www.debian.org/security/2018/dsa-4213 https://access.redhat.com/security/cve/CVE-2017-15119 https:/ • CWE-400: Uncontrolled Resource Consumption •

FasterXML jackson-databind through 2.8.11 and 2.9.x through 2.9.3 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 and CVE-2017-17485 deserialization flaws. This is exploitable via two different gadgets that bypass a blacklist. FasterXML jackson-databind, hasta la versión 2.8.11 y las versiones 2.9.x hasta la 2.9.3, permite la ejecución remota de código sin autenticar debido a una solución incompleta para los errores de deserialización CVE-2017-7525 y CVE-2017-17485. Esto es explotable mediante dos gadgets diferentes que omiten una lista negra.

CVSS: 7.0EPSS: 0%CPEs: 17EXPL: 0CVE-2017-7536 – hibernate-validator: Privilege escalation when running under the security manager
https://notcve.org/view.php?id=CVE-2017-7536
In Hibernate Validator 5.2.x before 5.2.5 final, 5.3.x, and 5.4.x, it was found that when the security manager's reflective permissions, which allows it to access the private members of the class, are granted to Hibernate Validator, a potential privilege escalation can occur. By allowing the calling code to access those private members without the permission an attacker may be able to validate an invalid instance and access the private member value via ConstraintViolation#getInvalidValue(). En Hibernate Validator 5.2.x anteriores a 5.2.5 final, 5.3.x y 5.4.x, se ha detectado que cuando los permisos reflectivos del gestor de seguridad, el cual accede a los miembros privados de la clase, se conceden a Hibernate Validator, podría ocurrir un escalado de privilegios. Permitiendo que el código de llamada acceda a esos miembros privados sin ningún permiso, el atacante podría validar una instancia no válida y acceder al valor del miembro privado mediante ConstraintViolation#getInvalidValue().

https://notcve.org/view.php?id=CVE-2017-7539
An assertion-failure flaw was found in Qemu before 2.10.1, in the Network Block Device (NBD) server's initial connection negotiation, where the I/O coroutine was undefined. This could crash the qemu-nbd server if a client sent unexpected data during connection negotiation. A remote user or process could use this flaw to crash the qemu-nbd server resulting in denial of service. Se ha detectado un fallo de aserción en Qemu en versiones anteriores a la 2.10.1 en la negociación de conexión inicial de los servidores de NBD (Network Block Device) en el que la corrutina I/O no estaba definida. Esto podría provocar el cierre inesperado del servidor qemu-nbd si un cliente envía datos no esperados durante la negociación de la conexión. • http://www.openwall.com/lists/oss-security/2017/07/21/4 http://www.securityfocus.com/bid/99944 https://access.redhat.com/errata/RHSA-2017:2628 https://access.redhat.com/errata/RHSA-2017:3466 https://access.redhat.com/errata/RHSA-2017:3470 https://access.redhat.com/errata/RHSA-2017:3471 https://access.redhat.com/errata/RHSA-2017:3472 https://access.redhat.com/errata/RHSA-2017:3473 https://access.redhat.com/errata/RHSA-2017:3474 https://bugzilla.redhat.com/show_b • CWE-20: Improper Input Validation CWE-617: Reachable Assertion •
