CVE-2014-0143

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.
