CVE-2016-1922 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2020-11-10 | 2.1 LOW | 5.5 MEDIUM |
QEMU (aka Quick Emulator) built with the TPR optimization for 32-bit Windows guests support is vulnerable to a null pointer dereference flaw. It occurs while doing I/O port write operations via hmp interface. In that, 'current_cpu' remains null, which leads to the null pointer dereference. A user or process could use this flaw to crash the QEMU instance, resulting in DoS issue. | |||||
CVE-2016-9776 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2020-11-10 | 2.1 LOW | 5.5 MEDIUM |
QEMU (aka Quick Emulator) built with the ColdFire Fast Ethernet Controller emulator support is vulnerable to an infinite loop issue. It could occur while receiving packets in 'mcf_fec_receive'. A privileged user/process inside guest could use this issue to crash the QEMU process on the host leading to DoS. | |||||
CVE-2017-13672 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2020-11-10 | 2.1 LOW | 5.5 MEDIUM |
QEMU (aka Quick Emulator), when built with the VGA display emulator support, allows local guest OS privileged users to cause a denial of service (out-of-bounds read and QEMU process crash) via vectors involving display update. | |||||
CVE-2017-12809 | 2 Debian, Qemu | 2 Debian Linux, Qemu | 2020-11-10 | 2.1 LOW | 6.5 MEDIUM |
QEMU (aka Quick Emulator), when built with the IDE disk and CD/DVD-ROM Emulator support, allows local guest OS privileged users to cause a denial of service (NULL pointer dereference and QEMU process crash) by flushing an empty CDROM device drive. | |||||
