Summary
[none]
Details

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 parallelsopen function in block/parallels.c or (2) bochsopen function in bochs.c, a large L1 table in the (3) qcow2snapshotloadtmp in qcow2-snapshot.c or (4) qcow2growl1table function in qcow2-cluster.c, (5) a large request in the bdrvcheckbyterequest function in block.c and other block drivers, (6) crafted cluster indexes in the getrefcount 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.
