| CVE-2019-5008 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| hw/sparc64/sun4u.c in QEMU 3.1.50 is vulnerable to a NULL pointer dereference, which allows the attacker to cause a denial of service via a device driver. | |||||

| 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-2019-20808 | 1 Qemu | 1 Qemu | 2024-11-21 | 2.1 LOW | 6.5 MEDIUM |
| In QEMU 4.1.0, an out-of-bounds read flaw was found in the ATI VGA implementation. It occurs in the ati_cursor_define() routine while handling MMIO write operations through the ati_mm_write() callback. A malicious guest could abuse this flaw to crash the QEMU process, resulting in a denial of service. | |||||
| CVE-2019-20382 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 2.7 LOW | 3.5 LOW |
| QEMU 4.1.0 has a memory leak in zrle_compress_data in ui/vnc-enc-zrle.c during a VNC disconnect operation because libz is misused, resulting in a situation where memory allocated in deflateInit2 is not freed in deflateEnd. | |||||
| CVE-2019-20175 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| 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-2019-15890 | 2 Libslirp Project, Qemu | 2 Libslirp, Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| libslirp 4.0.0, as used in QEMU 4.1.0, has a use-after-free in ip_reass in ip_input.c. | |||||
| CVE-2019-15034 | 1 Qemu | 1 Qemu | 2024-11-21 | 4.4 MEDIUM | 5.8 MEDIUM |
| hw/display/bochs-display.c in QEMU 4.0.0 does not ensure a sufficient PCI config space allocation, leading to a buffer overflow involving the PCIe extended config space. | |||||
| CVE-2019-13164 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 4.6 MEDIUM | 7.8 HIGH |
| qemu-bridge-helper.c in QEMU 3.1 and 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-2019-12929 | 1 Qemu | 1 Qemu | 2024-11-21 | 10.0 HIGH | 9.8 CRITICAL |
| 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-2019-12928 | 1 Qemu | 1 Qemu | 2024-11-21 | 10.0 HIGH | 9.8 CRITICAL |
| 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-2019-12247 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| QEMU 3.0.0 has an Integer Overflow because the qga/commands*.c files do not check the length of the argument list or the number of environment variables. NOTE: This has been disputed as not exploitable | |||||
| CVE-2019-12155 | 1 Qemu | 1 Qemu | 2024-11-21 | 5.0 MEDIUM | 7.5 HIGH |
| interface_release_resource in hw/display/qxl.c in QEMU 3.1.x through 4.0.0 has a NULL pointer dereference. | |||||
| CVE-2019-12068 | 4 Canonical, Debian, Opensuse and 1 more | 4 Ubuntu Linux, Debian Linux, Leap and 1 more | 2024-11-21 | 2.1 LOW | 3.8 LOW |
| 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-2019-12067 | 4 Debian, Fedoraproject, Qemu and 1 more | 5 Debian Linux, Fedora, Qemu and 2 more | 2024-11-21 | 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-2018-7858 | 4 Canonical, Opensuse, Qemu and 1 more | 9 Ubuntu Linux, Leap, Qemu and 6 more | 2024-11-21 | 2.1 LOW | 5.5 MEDIUM |
| Quick Emulator (aka QEMU), when built with the Cirrus CLGD 54xx VGA Emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds access and QEMU process crash) by leveraging incorrect region calculation when updating VGA display. | |||||
| CVE-2018-7550 | 4 Canonical, Debian, Qemu and 1 more | 9 Ubuntu Linux, Debian Linux, Qemu and 6 more | 2024-11-21 | 4.6 MEDIUM | 8.8 HIGH |
| The load_multiboot function in hw/i386/multiboot.c in Quick Emulator (aka QEMU) allows local guest OS users to execute arbitrary code on the QEMU host via a mh_load_end_addr value greater than mh_bss_end_addr, which triggers an out-of-bounds read or write memory access. | |||||
| CVE-2018-5683 | 4 Canonical, Debian, Qemu and 1 more | 9 Ubuntu Linux, Debian Linux, Qemu and 6 more | 2024-11-21 | 2.1 LOW | 6.0 MEDIUM |
| The vga_draw_text function in Qemu allows local OS guest privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) by leveraging improper memory address validation. | |||||
| CVE-2018-20815 | 1 Qemu | 1 Qemu | 2024-11-21 | 7.5 HIGH | 9.8 CRITICAL |
| In QEMU 3.1.0, load_device_tree in device_tree.c calls the deprecated load_image function, which has a buffer overflow risk. | |||||
