An assertion failure issue was found in the Network Block Device(NBD) Server in all QEMU versions before QEMU 5.0.1. This flaw occurs when an nbd-client sends a spec-compliant request that is near the boundary of maximum permitted request length. A remote nbd-client could use this flaw to crash the qemu-nbd server resulting in a denial of service. Se encontró un problema de fallo de aserción en el Network Block Device (NBD) en todas las versiones de QEMU anteriores a QEMU versión 5.0.1. Este fallo ocurre cuando un cliente nbd envía una petición que cumple con las especificaciones que está cerca del límite de la longitud máxima permitida de la petición. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00086.html https://bugzilla.redhat.com/show_bug.cgi?id=CVE-2020-10761 https://security.gentoo.org/glsa/202011-09 https://security.netapp.com/advisory/ntap-20200731-0001 https://usn.ubuntu.com/4467-1 https://www.openwall.com/lists/oss-security/2020/06/09/1 • CWE-617: Reachable Assertion •
