Descriptions
The (1) BMDMA and (2) AHCI HBA interfaces in the IDE functionality in QEMU 1.0 through 2.1.3 have multiple interpretations of a function's return value, which allows guest OS users to cause a host OS denial of service (memory consumption or infinite loop, and system crash) via a PRDT with zero complete sectors, related to the bmdma_prepare_buf and ahci_dma_prepare_buf functions.
Las interfaces (1) BMDMA y (2) AHCI HBA en la funcionalidad IDE en QEMU 1.0 hasta 2.1.3 tienen múltiples interpretaciones del valor de retorno de una función, lo que permite a usarios del sistema operativo invitado causar una denegación de servicio en el sistema operativo del anfitrión (corrupción de memoria o bucle infinito, y caída del sistema) a través de un PRDT sin ningun sector completo, relacionado con las funciones bmdma_prepare_buf y ahci_dma_prepare_buf.
It was discovered that QEMU incorrectly handled a PRDT with zero complete sectors in the IDE functionality. A malicious guest could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 12.04 LTS and Ubuntu 14.04 LTS. Donghai Zhu discovered that QEMU incorrectly handled the RTL8139 driver. A malicious guest could possibly use this issue to read sensitive information from arbitrary host memory. Various other issues were also addressed.
