The (1) v9fs_create and (2) v9fs_lcreate functions in hw/9pfs/9p.c in QEMU (aka Quick Emulator) allow local guest OS privileged users to cause a denial of service (file descriptor or memory consumption) via vectors related to an already in-use fid.
CVE-2017-8112 2 Debian, Qemu 2 Debian Linux, Qemu 2020-09-10 4.9 MEDIUM 6.5 MEDIUM
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-2017-8086 2 Debian, Qemu 2 Debian Linux, Qemu 2020-09-10 4.9 MEDIUM 6.5 MEDIUM
Memory leak in the v9fs_list_xattr function in hw/9pfs/9p-xattr.c in QEMU (aka Quick Emulator) allows local guest OS privileged users to cause a denial of service (memory consumption) via vectors involving the orig_value variable.
CVE-2018-15746 1 Qemu 1 Qemu 2020-09-10 2.1 LOW 5.5 MEDIUM
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-2018-17958 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2020-09-10 5.0 MEDIUM 7.5 HIGH
Qemu has a Buffer Overflow in rtl8139_do_receive in hw/net/rtl8139.c because an incorrect integer data type is used.
CVE-2015-4106 6 Canonical, Citrix, Debian and 3 more 8 Ubuntu Linux, Xenserver, Debian Linux and 5 more 2020-09-09 4.6 MEDIUM N/A
QEMU does not properly restrict write access to the PCI config space for certain PCI pass-through devices, which might allow local x86 HVM guests to gain privileges, cause a denial of service (host crash), obtain sensitive information, or possibly have other unspecified impact via unknown vectors.
CVE-2015-7295 3 Debian, Fedoraproject, Qemu 3 Debian Linux, Fedora, Qemu 2020-09-09 5.0 MEDIUM N/A
hw/virtio/virtio.c in the Virtual Network Device (virtio-net) support in QEMU, when big or mergeable receive buffers are not supported, allows remote attackers to cause a denial of service (guest network consumption) via a flood of jumbo frames on the (1) tuntap or (2) macvtap interface.
CVE-2015-8567 6 Canonical, Debian, Fedoraproject and 3 more 10 Ubuntu Linux, Debian Linux, Fedora and 7 more 2020-09-09 6.8 MEDIUM 7.7 HIGH
Memory leak in net/vmxnet3.c in QEMU allows remote attackers to cause a denial of service (memory consumption).

Stack-based buffer overflow in hw/scsi/scsi-bus.c in QEMU, when built with SCSI-device emulation support, allows guest OS users with CAP_SYS_RAWIO permissions to cause a denial of service (instance crash) via an invalid opcode in a SCSI command descriptor block.
CVE-2020-14415 2 Canonical, Qemu 2 Ubuntu Linux, Qemu 2020-09-02 2.1 LOW 3.3 LOW
oss_write in audio/ossaudio.c in QEMU before 5.0.0 mishandles a buffer position.
CVE-2019-12929 1 Qemu 1 Qemu 2020-08-24 10.0 HIGH 9.8 CRITICAL
** DISPUTED ** The QMP guest_exec command in QEMU 4.0.0 and earlier is prone to OS command injection, which allows the attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue.
CVE-2019-9824 1 Qemu 1 Qemu 2020-08-24 2.1 LOW 5.5 MEDIUM
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-2019-12928 1 Qemu 1 Qemu 2020-08-24 10.0 HIGH 9.8 CRITICAL
** DISPUTED ** The QMP migrate command in QEMU version 4.0.0 and earlier is vulnerable to OS command injection, which allows the remote attacker to achieve code execution, denial of service, or information disclosure by sending a crafted QMP command to the listening server. Note: This has been disputed as a non-issue since QEMU's -qmp interface is meant to be used by trusted users. If one is able to access this interface via a tcp socket open to the internet, then it is an insecure configuration issue.
CVE-2018-17962 6 Canonical, Debian, Oracle and 3 more 6 Ubuntu Linux, Debian Linux, Linux and 3 more 2020-08-24 5.0 MEDIUM 7.5 HIGH
Qemu has a Buffer Overflow in pcnet_receive in hw/net/pcnet.c because an incorrect integer data type is used.
CVE-2019-6778 4 Canonical, Fedoraproject, Opensuse and 1 more 4 Ubuntu Linux, Fedora, Leap and 1 more 2020-08-24 4.6 MEDIUM 7.8 HIGH
In QEMU 3.0.0, tcp_emu in slirp/tcp_subr.c has a heap-based buffer overflow.
