hw/usb/hcd-ohci.c in QEMU 5.0.0 has a stack-based buffer over-read via values obtained from the host controller driver.
CVE-2020-35505 2 Debian, Qemu 2 Debian Linux, Qemu 2022-09-22 2.1 LOW 4.4 MEDIUM
A NULL pointer dereference flaw was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0. This issue occurs while handling the 'Information Transfer' command. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-35504 3 Debian, Fedoraproject, Qemu 3 Debian Linux, Fedora, Qemu 2022-09-22 2.1 LOW 6.0 MEDIUM
A NULL pointer dereference flaw was found in the SCSI emulation support of QEMU in versions before 6.0.0. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-35506 1 Qemu 1 Qemu 2022-08-31 4.6 MEDIUM 6.7 MEDIUM
A use-after-free vulnerability was found in the am53c974 SCSI host bus adapter emulation of QEMU in versions before 6.0.0 during the handling of the 'Information Transfer' command (CMD_TI). This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service or potential code execution with the privileges of the QEMU process.
CVE-2021-20255 2 Debian, Qemu 2 Debian Linux, Qemu 2022-08-05 2.1 LOW 5.5 MEDIUM
A stack overflow via an infinite recursion vulnerability was found in the eepro100 i8255x device emulator of QEMU. This issue occurs while processing controller commands due to a DMA reentry issue. This flaw allows a guest user or process to consume CPU cycles or crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2015-5239 5 Arista, Canonical, Fedoraproject and 2 more 8 Eos, Ubuntu Linux, Fedora and 5 more 2022-06-05 4.0 MEDIUM 6.5 MEDIUM
Integer overflow in the VNC display driver in QEMU before 2.1.0 allows attachers to cause a denial of service (process crash) via a CLIENT_CUT_TEXT message, which triggers an infinite loop.
CVE-2019-12067 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Qemu and 2 more 2022-05-13 2.1 LOW 6.5 MEDIUM
The ahci_commit_buf function in ide/ahci.c in QEMU allows attackers to cause a denial of service (NULL dereference) when the command header 'ad->cur_cmd' is null.
CVE-2020-35503 2 Fedoraproject, Qemu 2 Fedora, Qemu 2022-05-13 2.1 LOW 6.0 MEDIUM
A NULL pointer dereference flaw was found in the megasas-gen2 SCSI host bus adapter emulation of QEMU in versions before and including 6.0. This issue occurs in the megasas_command_cancelled() callback function while dropping a SCSI request. This flaw allows a privileged guest user to crash the QEMU process on the host, resulting in a denial of service. The highest threat from this vulnerability is to system availability.
CVE-2020-13800 3 Canonical, Opensuse, Qemu 3 Ubuntu Linux, Leap, Qemu 2022-04-28 4.9 MEDIUM 6.0 MEDIUM
ati-vga in hw/display/ati.c in QEMU 4.2.0 allows guest OS users to trigger infinite recursion via a crafted mm_index value during an ati_mm_read or ati_mm_write call.
CVE-2019-8934 2 Opensuse, Qemu 2 Leap, Qemu 2022-04-05 2.1 LOW 3.3 LOW
hw/ppc/spapr.c in QEMU through 3.1.0 allows Information Exposure because the hypervisor shares the /proc/device-tree/system-id and /proc/device-tree/model system attributes with a guest.
CVE-2015-5745 3 Arista, Fedoraproject, Qemu 3 Eos, Fedora, Qemu 2022-02-20 4.0 MEDIUM 6.5 MEDIUM
Buffer overflow in the send_control_msg function in hw/char/virtio-serial-bus.c in QEMU before 2.4.0 allows guest users to cause a denial of service (QEMU process crash) via a crafted virtio control message.
CVE-2020-27616 1 Qemu 1 Qemu 2022-01-01 4.0 MEDIUM 6.5 MEDIUM
ati_2d_blt in hw/display/ati_2d.c in QEMU 4.2.1 can encounter an outside-limits situation in a calculation. A guest can crash the QEMU process.
CVE-2015-6855 6 Arista, Canonical, Debian and 3 more 7 Eos, Ubuntu Linux, Debian Linux and 4 more 2021-12-15 5.0 MEDIUM 7.5 HIGH
hw/ide/core.c in QEMU does not properly restrict the commands accepted by an ATAPI device, which allows guest users to cause a denial of service or possibly have unspecified other impact via certain IDE commands, as demonstrated by a WIN_READ_NATIVE_MAX command to an empty drive, which triggers a divide-by-zero error and instance crash.
CVE-2015-5278 4 Arista, Canonical, Fedoraproject and 1 more 4 Eos, Ubuntu Linux, Fedora and 1 more 2021-11-30 4.0 MEDIUM 6.5 MEDIUM
The ne2000_receive function in hw/net/ne2000.c in QEMU before 2.4.0.1 allows attackers to cause a denial of service (infinite loop and instance crash) or possibly execute arbitrary code via vectors related to receiving packets.
