Heap-based buffer overflow in Cirrus CLGD 54xx VGA Emulator in Quick Emulator (Qemu) 2.8 and earlier allows local guest OS users to execute arbitrary code or cause a denial of service (crash) via vectors related to a VNC client updating its display after a VGA operation.
CVE-2018-18438 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2021-08-04 2.1 LOW 5.5 MEDIUM
Qemu has integer overflows because IOReadHandler and its associated functions use a signed integer data type for a size value.
CVE-2017-10664 3 Debian, Qemu, Redhat 11 Debian Linux, Qemu, Enterprise Linux and 8 more 2021-08-04 5.0 MEDIUM 7.5 HIGH
qemu-nbd in QEMU (aka Quick Emulator) does not ignore SIGPIPE, which allows remote attackers to cause a denial of service (daemon crash) by disconnecting during a server-to-client reply attempt.
CVE-2017-8309 3 Debian, Qemu, Redhat 3 Debian Linux, Qemu, Openstack 2021-08-04 7.8 HIGH 7.5 HIGH
Memory leak in the audio/audio.c in QEMU (aka Quick Emulator) allows remote attackers to cause a denial of service (memory consumption) by repeatedly starting and stopping audio capture.
CVE-2016-5403 5 Canonical, Debian, Oracle and 2 more 13 Ubuntu Linux, Debian Linux, Linux and 10 more 2021-08-04 4.9 MEDIUM 5.5 MEDIUM
The virtqueue_pop function in hw/virtio/virtio.c in QEMU allows local guest OS administrators to cause a denial of service (memory consumption and QEMU process crash) by submitting requests without waiting for completion.
CVE-2016-3710 7 Canonical, Citrix, Debian and 4 more 15 Ubuntu Linux, Xenserver, Debian Linux and 12 more 2021-08-04 7.2 HIGH 8.8 HIGH
The VGA module in QEMU improperly performs bounds checking on banked access to video memory, which allows local guest OS administrators to execute arbitrary code on the host by changing access modes after setting the bank register, aka the "Dark Portal" issue.
CVE-2018-17963 4 Canonical, Debian, Qemu and 1 more 6 Ubuntu Linux, Debian Linux, Qemu and 3 more 2021-08-04 7.5 HIGH 9.8 CRITICAL
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-2020-24352 1 Qemu 1 Qemu 2021-07-21 2.1 LOW 5.5 MEDIUM
An issue was discovered in QEMU through 5.1.0. An out-of-bounds memory access was found in the ATI VGA device implementation. This flaw occurs in the ati_2d_blt() routine in hw/display/ati_2d.c while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could use this flaw to crash the QEMU process on the host, resulting in a denial of service.
CVE-2017-5957 2 Qemu, Virglrenderer Project 2 Qemu, Virglrenderer 2021-05-19 2.1 LOW 5.5 MEDIUM
Stack-based buffer overflow in the vrend_decode_set_framebuffer_state function in vrend_decode.c in virglrenderer before 926b9b3460a48f6454d8bbe9e44313d86a65447f, as used in Quick Emulator (QEMU), allows a local guest users to cause a denial of service (application crash) via the "nr_cbufs" argument.
CVE-2020-7039 4 Debian, Libslirp Project, Opensuse and 1 more 4 Debian Linux, Libslirp, Leap and 1 more 2021-02-14 6.8 MEDIUM 5.6 MEDIUM
tcp_emu in tcp_subr.c in libslirp 4.1.0, as used in QEMU 4.2.0, mismanages memory, as demonstrated by IRC DCC commands in EMU_IRC. This can cause a heap-based buffer overflow or other out-of-bounds access which can lead to a DoS or potential execute arbitrary code.
CVE-2008-1945 6 Canonical, Debian, Opensuse and 3 more 9 Ubuntu Linux, Debian Linux, Opensuse and 6 more 2020-12-16 2.1 LOW N/A
QEMU 0.9.0 does not properly handle changes to removable media, which allows guest OS users to read arbitrary files on the host OS by using the diskformat: parameter in the -usbdevice option to modify the disk-image header to identify a different format, a related issue to CVE-2008-2004.
CVE-2007-1320 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Fedora Core and 3 more 2020-12-15 7.2 HIGH N/A
Multiple heap-based buffer overflows in the cirrus_invalidate_region function in the Cirrus VGA extension in QEMU 0.8.2, as used in Xen and possibly other products, might allow local users to execute arbitrary code via unspecified vectors related to "attempting to mark non-existent regions as dirty," aka the "bitblt" heap overflow.
CVE-2007-1321 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Fedora Core and 2 more 2020-12-15 7.2 HIGH N/A
Integer signedness error in the NE2000 emulator in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to trigger a heap-based buffer overflow via certain register values that bypass sanity checks, aka QEMU NE2000 "receive" integer signedness error. NOTE: this identifier was inadvertently used by some sources to cover multiple issues that were labeled "NE2000 network driver and the socket code," but separate identifiers have been created for the individual vulnerabilities since there are sometimes different fixes; see CVE-2007-5729 and CVE-2007-5730.
CVE-2007-1322 2 Debian, Qemu 2 Debian Linux, Qemu 2020-12-15 2.1 LOW N/A
QEMU 0.8.2 allows local users to halt a virtual machine by executing the icebp instruction.
CVE-2007-1366 2 Debian, Qemu 2 Debian Linux, Qemu 2020-12-15 2.1 LOW N/A
QEMU 0.8.2 allows local users to crash a virtual machine via the divisor operand to the aam instruction, as demonstrated by "aam 0x0," which triggers a divide-by-zero error.
CVE-2007-5729 3 Debian, Opensuse, Qemu 3 Debian Linux, Opensuse, Qemu 2020-12-15 7.2 HIGH N/A
The NE2000 emulator in QEMU 0.8.2 allows local users to execute arbitrary code by writing Ethernet frames with a size larger than the MTU to the EN0_TCNT register, which triggers a heap-based buffer overflow in the slirp library, aka NE2000 "mtu" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the mtu overflow vulnerability.
CVE-2007-5730 3 Debian, Qemu, Xen 3 Debian Linux, Qemu, Xen 2020-12-15 7.2 HIGH N/A
Heap-based buffer overflow in QEMU 0.8.2, as used in Xen and possibly other products, allows local users to execute arbitrary code via crafted data in the "net socket listen" option, aka QEMU "net socket" heap overflow. NOTE: some sources have used CVE-2007-1321 to refer to this issue as part of "NE2000 network driver and the socket code," but this is the correct identifier for the individual net socket listen vulnerability.
CVE-2020-13791 1 Qemu 1 Qemu 2020-12-14 2.1 LOW 5.5 MEDIUM
hw/pci/pci.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access by providing an address near the end of the PCI configuration space.
CVE-2020-13754 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-12-14 4.6 MEDIUM 6.7 MEDIUM
hw/pci/msix.c in QEMU 4.2.0 allows guest OS users to trigger an out-of-bounds access via a crafted address in an msi-x mmio operation.
CVE-2020-12829 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2020-12-14 2.1 LOW 3.8 LOW
In QEMU through 5.0.0, an integer overflow was found in the SM501 display driver implementation. This flaw occurs in the COPY_AREA macro while handling MMIO write operations through the sm501_2d_engine_write() callback. A local attacker could abuse this flaw to crash the QEMU process in sm501_2d_operation() in hw/display/sm501.c on the host, resulting in a denial of service.
