CVE-2018-20856

El servidor web en ZENworks Configuration Management (ZCM) de Novell versión 10.3 y versión 11.2 anteriores a 11.2.4, no realiza apropiadamente la autenticación para el archivo zenworks/jsp/index.jsp, lo que permite a los atacantes remotos realizar ataques de salto de directorio y en consecuencia cargar y ejecutar programas arbitrarios, por medio de una petición al puerto TCP 443.

A flaw was found in the Linux kernel’s block driver implementation (blk_drain_queue() function) where a use-after-free condition could be triggered while draining the outstanding command queue in the systems block device subsystem. An attacker could use this flaw to crash the system or corrupt local memory, which may lead to privilege escalation.

It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service or possibly execute arbitrary code. Amit Klein and Benny Pinkas discovered that the Linux kernel did not sufficiently randomize IP ID values generated for connectionless networking protocols. A remote attacker could use this to track particular Linux devices. Various other issues were also addressed.
