CVE-2017-10664

Heap-based buffer overflow in the pcnet_receive function in hw/net/pcnet.c in QEMU allows guest OS administrators to cause a denial of service (instance crash) or possibly execute arbitrary code via a series of packets in loopback mode.

Qemu through 2.10.0 allows remote attackers to cause a memory leak by triggering slow data-channel read operations, related to io/channel-websock.c.

A use-after-free vulnerability in the sofree function in slirp/socket.c in QEMU allows attackers to cause a denial of service (QEMU instance crash) by failing to properly clear ifq_so from pending packets.

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 L1 table in the qcow2_snapshot_load_tmp in the QCOW 2 block driver or various parameters in the DMG block driver.

Multiple integer overflows in QEMU, before version 2.0.0, allow local users to cause a denial of service (crash) by providing crafted input, leading to buffer overflows and memory corruption.

A memory leak in audio/audio.c in QEMU allows remote attackers to cause a denial of service by repeatedly starting and stopping audio capture.

The disas_insn function in QEMU before version 2.9.0 does not limit instruction size in TCG mode without hardware acceleration, allowing local users to gain privileges by creating a modified basic block that injects code into a setuid program.

The Human Monitor Interface support in QEMU allows remote attackers to cause a denial of service through out-of-bounds write and application crash.

A memory leak in QEMU's net/vmxnet3.c allows remote attackers to cause a denial of service through excessive memory consumption.

A heap-based buffer overflow exists in QEMU when built with the Q35-chipset-based PC system emulator. This vulnerability may lead to unauthorized memory access.
