Descriptions

Multiple buffer overflows in QEMU before 1.7.2 and 2.x before 2.0.0, allow local users to cause a denial of service (crash) or possibly execute arbitrary code via a large (1) L1 table in the qcow2_snapshot_load_tmp in the QCOW 2 block driver (block/qcow2-snapshot.c) or (2) uncompressed chunk, (3) chunk length, or (4) number of sectors in the DMG block driver (block/dmg.c).

Múltiples desbordamientos de búfer en QEMU en versiones anteriores a la 1.7.2 y en versiones 2.x anteriores a la 2.0.0 permiten que usuarios locales provoquen una denegación de servicio o que puedan ejecutar código arbitrario mediante una gran (1) tabla L1 en qcow2_snapshot_load_tmp en el controlador de bloque QCOW 2 (block/qcow2-snapshot.c) o (2) fragmento sin comprimir, (3) tamaño de fragmento, o (4) número de sectores en el controlador de bloque DMG (block/dmg.c).
