script_tag(name:"insight", value:"In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.(CVE-2019-6778)
The MSI-X MMIO support in hw/pci/msix.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) by leveraging failure to define the .write method.(CVE-2015-7549)
The ne2000_receive function in the NE2000 NIC emulation support (hw/net/ne2000.c) in QEMU before 2.5.1 allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via crafted values for the PSTART and PSTOP registers, involving ring buffer control.(CVE-2016-2841)
Memory leak in QEMU (aka Quick Emulator), when built with USB EHCI Emulation support, allows local guest OS privileged users to cause a denial of service (memory consumption) by repeatedly hot-unplugging the device.(CVE-2017-9374)
Integer overflow in the macro ROUND_UP (n, d) in Quick Emulator (Qemu) allows a user to cause a denial of service (Qemu process crash).(CVE-2017-18043)
Memory leak in the serial_exit_core function in hw/char/serial.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (host memory consumption and QEMU process crash) via a large number of device unplug operations.(CVE-2017-5579)
The slirp_smb function in net/slirp.c in QEMU 2.3.0 and earlier creates temporary files with predictable names, which allows local users to cause a denial of service (instantiation failure) by creating /tmp/qemu-smb.*-* files before the program.(CVE-2015-4037)
The mcf_fec_do_tx function in hw/net/mcf_fec.c in QEMU (aka Quick Emulator) does not properly limit the buffer descriptor count when transmitting packets, which allows local guest OS administrators to cause a denial of service (infinite loop and QEMU process crash) via vectors involving a buffer descriptor with a length of 0 and crafted values in bd.flags.(CVE-2016-7908)
hw/net/vmxnet3.c in QEMU 2.0.0-rc0, 1.7.1, and earlier allows local guest users to cause a denial of service or possibly execute arbitrary code via vectors related to (1) RX or (2) TX queue numbers or (3) interrupt indices. NOTE: some of these details are obtained from third party information.(CVE-2013-4544)
Multiple integer overflows in the USB Net device emulator (hw/usb/dev-network.c) in QEMU before 2.5.1 allow local guest OS administrators to cause a denial of service (QEMU process crash) or obtain sensitive host memory information via a remote NDIS control message packet that is mishandled in the (1) rndis_query_response, (2) rndis_set_response, or (3) usb_net_handle_dataout function.(CVE-2016-2538)
Qemu emulator <= 3.0.0 built with the NE2000 NIC emulation support is vulnerable to an integer overflow, which could lead to buffer overflow issue. It could occur when receiving packets over the network. A user inside guest could use this flaw to crash ... [Please see the references for more information on the vulnerabilities]");
