Descriptions
Multiple integer overflows in the block drivers in QEMU, possibly before 2.0.0, allow local users to cause a denial of service (crash) via a crafted catalog size in (1) the parallels_open function in block/parallels.c or (2) bochs_open function in bochs.c, a large L1 table in the (3) qcow2_snapshot_load_tmp in qcow2-snapshot.c or (4) qcow2_grow_l1_table function in qcow2-cluster.c, (5) a large request in the bdrv_check_byte_request function in block.c and other block drivers, (6) crafted cluster indexes in the get_refcount function in qcow2-refcount.c, or (7) a large number of blocks in the cloop_open function in cloop.c, which trigger buffer overflows, memory corruption, large memory allocations and out-of-bounds read and writes.
Múltiples desbordamientos de enteros en los controladores de bloque en QEMU, posiblemente en versiones anteriores a la 2.0.0, permiten que usuarios locales provoquen una denegación de servicio mediante un tamaño de catálogo manipulado en (1) la función parallels_open en block/parallels.c o (2) la función bochs_open en bochs.c, una gran tabla en (3) qcow2_snapshot_load_tmp en qcow2-snapshot.c o en la función (4) qcow2_grow_l1_table en qcow2-cluster.c, (5) una gran petición en la función bdrv_check_byte_request en block.c y otros controladores de bloqueo, (6) índices de clúster manipulados en la función get_refcount en qcow2-refcount.c, o (7) un gran número de bloqueos en la función cloop_open en cloop.c. Esto provoca desbordamientos de búfer, corrupción de memoria, grandes asignaciones de memoria y lesturas y escrituras fuera de límites.
