  - The xhci_kick_epctx function in hw/usb/hcd-xhci.c in     QEMU (aka Quick Emulator) allows local guest OS     privileged users to cause a denial of service (infinite     loop and QEMU process crash) via vectors related to     control transfer descriptor sequence.(CVE-2017-5973)

  - The sdhci_sdma_transfer_multi_blocks function in     hw/sd/sdhci.c in QEMU (aka Quick Emulator) allows local     OS guest privileged users to cause a denial of service     (infinite loop and QEMU process crash) via vectors     involving the transfer mode register during multi block     transfer.(CVE-2017-5987)

  - Memory leak in the megasas_handle_dcmd function in     hw/scsi/megasas.c in QEMU (aka Quick Emulator) allows     local guest OS privileged users to cause a denial of     service (host memory consumption) via MegaRAID Firmware     Interface (MFI) commands with the sglist size set to a     value over 2 Gb.(CVE-2017-5856)

  - qemu_deliver_packet_iov in net/net.c in Qemu accepts     packet sizes greater than INT_MAX, which allows     attackers to cause a denial of service or possibly have     unspecified other impact.(CVE-2018-17963)

  - qemu-bridge-helper.c in QEMU 4.0.0 does not ensure that     a network interface name (obtained from bridge.conf or     a --br=bridge option) is limited to the IFNAMSIZ size,     which can lead to an ACL bypass.(CVE-2019-13164)

  - Buffer overflow in the 'megasas_mmio_write' function in     Qemu 2.9.0 allows remote attackers to have unspecified     impact via unknown vectors.(CVE-2017-8380)

  - Quick Emulator (Qemu) built with the VirtFS, host     directory sharing via Plan 9 File System(9pfs) support,     is vulnerable to an improper access control issue. It     could occur while accessing virtfs metadata files in     mapped-file security mode. A guest user could use this     flaw to escalate their privileges inside     guest.(CVE-2017-7493)

  - In QEMU 3.1.0, load_device_tree in device_tree.c calls     the deprecated load_image function, which has a buffer     overflow risk.(CVE-2018-20815)

  - Use-after-free vulnerability in the sofree function in     slirp/socket.c in QEMU (aka Quick Emulator) allows     attackers to cause a denial of service (QEMU instance     crash) by leveraging failure to properly clear ifq_so     from pending packets.(CVE-2017-13711)

  - Stack-based buffer overflow in hw/usb/redirect.c in     QEMU (aka Quick Emulator) allows local guest OS users     to cause a denial of service (QEMU process crash) via     vectors related to logging debug     messages.(CVE-2017-10806)

  - The dhcp_decode function in slirp/bootp.c in QEMU (aka     Quick Emulator) allows local guest OS users to cause a     denial of service (out-of-bounds read and QEMU process     crash) via a crafted DHCP options     string.(CVE-2017-11434)

  - The imx_fec_do_tx function in hw/net/imx_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-2016-7907)

  - tcp_emu in slirp/tcp_subr.c (aka slirp/src/tcp_subr.c)     in QEMU 3.0.0 uses uninitialized data in an snprintf     call, leading to Information disclosure.(CVE-2019-9824)

  - interface_release_resource in hw/display/qxl.c in QEMU     4.0.0 has a NULL pointer dereference.(CVE-2019-12155)

  - hw/scsi/vmw_pvscsi.c in QEMU (aka Quick Emulator)     allows local guest OS privileged users to cause a     denial of service (infinite loop and CPU consumption)     via the message ring page count.(CVE-2017-8112)

  - Qemu has a Buffer Overflow in rtl8139_do_receive in     hw/net/rtl8139.c because an incorrect integer data type     is used.(CVE-2018-17958)

  - TSX Asynchronous Abort condition on some CPUs utilizing     speculative execution may allow an authenticated user     to potentially enable information disclosure via a side     channel with local access.(CVE-2019-11135)

  - In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6,     1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8~deb10u1,     1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12     (fixed), when executing script in lsi_execute_script(),     the LSI scsi adapter emulator advances 's->dsp' index     to read next opcode. This can lead to an infinite loop     if the next opcode is empty. Move the existing loop     exit after 10k iterations so that it covers no-op     opcodes as well.(CVE-2019-12068)

  - qemu-seccomp.c in QEMU might allow local OS guest users     to cause a denial of service (guest crash) by     leveraging mishandling of the seccomp policy for     threads other than the main thread.(CVE-2018-15746)

  - Qemu has a Buffer Overflow in pcnet_receive in     hw/net/pcnet.c because an incorrect integer data type     is used.(CVE-2018-17962)

  - Quick Emulator(Qemu) built with the VMWARE PVSCSI     paravirtual SCSI bus emulation support is vulnerable to     an OOB r/w access issue. It could occur while     processing SCSI commands 'PVSCSI_CMD_SETUP_RINGS' or     'PVSCSI_CMD_SETUP_MSG_RING'. A privileged user inside     guest could use this flaw to crash the Qemu process     resulting in DoS.(CVE-2016-4952)

  - m_cat in slirp/mbuf.c in Qemu has a heap-based buffer     overflow via incoming fragmented     datagrams.(CVE-2018-11806)

  - In Qemu 3.0.0, lsi_do_msgin in hw/scsi/lsi53c895a.c     allows out-of-bounds access by triggering an invalid     msg_len value.(CVE-2018-18849)

  - hw/9pfs/cofile.c and hw/9pfs/9p.c in QEMU can modify an     fid path while it is being accessed by a second thread,     leading to (for example) a use-after-free     outcome.(CVE-2018-19364)

  - v9fs_wstat in hw/9pfs/9p.c in QEMU allows guest OS     users to cause a denial of service (crash) because of a     race condition during file renaming.(CVE-2018-19489)

  - QEMU, through version 2.10 and through version 3.1.0,     is vulnerable to an out-of-bounds read of up to 128     bytes in the hw/i2c/i2c-ddc.c:i2c_ddc() function. A     local attacker with permission to execute i2c commands     could exploit this to read stack memory of the qemu     process on the host.(CVE-2019-3812)

  - A flaw was found in QEMU's Media Transfer Protocol     (MTP). The code opening files in usb_mtp_get_object and     usb_mtp_get_partial_object and directories in     usb_mtp_object_readdir doesn't consider that the     underlying filesystem may have changed since the time     lstat(2) was called in usb_mtp_object_alloc, a     classical TOCTTOU problem. An attacker with write     access to the host filesystem, shared with a guest, can     use this property to navigate the host filesystem in     the context of the QEMU process and read any file the     QEMU process has access to. Access to the filesystem     may be local or via a network share protocol such as     CIFS.(CVE-2018-16872)

  - ** DISPUTED ** An issue was discovered in ide_dma_cb()     in hw/ide/core.c in QEMU 2.4.0 through 4.2.0. The guest     system can crash the QEMU process in the host system     via a special SCSI_IOCTL_SEND_COMMAND. It hits an     assertion that implies that the size of successful DMA     transfers there must be a multiple of 512 (the size of     a sector). NOTE: a member of the QEMU security team     disputes the significance of this issue because a     'privileged guest user has many ways to cause similar     DoS effect, without triggering this     assert.'(CVE-2019-20175)

  - Quick Emulator (QEMU) built with Network Block Device     (NBD) Server support was vulnerable to a null-pointer     dereference issue. The flaw could occur when releasing     a client that was not initialized due to failed     negotiation. A remote user or process could exploit     this flaw to crash the qemu-nbd server (denial of     service).(CVE-2017-9524)

  - Qemu has integer overflows because IOReadHandler and     its associated functions use a signed integer data type     for a size value.(CVE-2018-18438)

  - The Bluetooth subsystem in QEMU mishandles negative     values for length variables, leading to memory     corruption.(CVE-2018-19665)

Fixed multiple access violations introduced by XENMEM_exchange hypercall which could allow a single PV guest to leak arbitrary amounts of memory, leading to a denial of service (bsc#1126192).

Fixed an issue which could allow malicious or buggy guests with passed through PCI devices to be able to escalate their privileges, crash the host, or access data belonging to other guests. Additionally memory leaks were also possible (bsc#1126140).

Fixed a race condition issue which could allow malicious PV guests to escalate their privilege to that of the hypervisor (bsc#1126141).

CVE-2019-9824: Fixed an information leak in SLiRP networking implementation which could allow a user/process to read uninitialised stack memory contents (bsc#1129623).
