CVE-2011-1751 1 Qemu 1 Qemu 2024-11-21 7.4 HIGH N/A
The pciej_write function in hw/acpi_piix4.c in the PIIX4 Power Management emulation in qemu-kvm does not check if a device is hotpluggable before unplugging the PCI-ISA bridge, which allows privileged guest users to cause a denial of service (guest crash) and possibly execute arbitrary code by sending a crafted value to the 0xae08 (PCI_EJ_BASE) I/O port, which leads to a use-after-free related to "active qemu timers."
CVE-2011-1750 1 Qemu 1 Qemu 2024-11-21 7.4 HIGH N/A
Multiple heap-based buffer overflows in the virtio-blk driver (hw/virtio-blk.c) in qemu-kvm 0.14.0 allow local guest users to cause a denial of service (guest crash) and possibly gain privileges via a (1) write request to the virtio_blk_handle_write function or (2) read request to the virtio_blk_handle_read function that is not properly aligned.
CVE-2011-0011 1 Qemu 1 Qemu 2024-11-21 4.3 MEDIUM N/A
qemu-kvm before 0.11.0 disables VNC authentication when the password is cleared, which allows remote attackers to bypass authentication and establish VNC sessions.
CVE-2010-0741 3 Kvm Qumranet, Linux, Qemu 3 Kvm, Linux Kernel, Qemu 2024-11-21 7.8 HIGH N/A
The virtio_net_bad_features function in hw/virtio-net.c in the virtio-net driver in the Linux kernel before 2.6.26, when used on a guest OS in conjunction with qemu-kvm 0.11.0 or KVM 83, allows remote attackers to cause a denial of service (guest OS crash, and an associated qemu-kvm process exit) by sending a large amount of network traffic to a TCP port on the guest OS, related to a virtio-net whitelist that includes an improper implementation of TCP Segment Offloading (TSO).
CVE-2010-0297 1 Qemu 1 Qemu 2024-11-21 7.2 HIGH N/A
Buffer overflow in the usb_host_handle_control function in the USB passthrough handling implementation in usb-linux.c in QEMU before 0.11.1 allows guest OS users to cause a denial of service (guest OS crash or hang) or possibly execute arbitrary code on the host OS via a crafted USB packet.
CVE-2009-3616 2 Qemu, Redhat 3 Qemu, Enterprise Linux Server, Enterprise Linux Workstation 2024-11-21 8.5 HIGH 9.9 CRITICAL
Multiple use-after-free vulnerabilities in vnc.c in the VNC server in QEMU 0.10.6 and earlier might allow guest OS users to execute arbitrary code on the host OS by establishing a connection from a VNC client and then (1) disconnecting during data transfer, (2) sending a message using incorrect integer data types, or (3) using the Fuzzy Screen Mode protocol, related to double free vulnerabilities.
CVE-2008-5714 1 Qemu 1 Qemu 2024-11-21 7.8 HIGH N/A
Off-by-one error in monitor.c in Qemu 0.9.1 might make it easier for remote attackers to guess the VNC password, which is limited to seven characters where eight was intended.
CVE-2008-4553 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 7.2 HIGH N/A
qemu-make-debian-root in qemu 0.9.1-5 on Debian GNU/Linux allows local users to overwrite arbitrary files via a symlink attack on temporary files and directories.
CVE-2008-4539 4 Canonical, Debian, Kvm Qumranet and 1 more 4 Ubuntu Linux, Debian Linux, Kvm and 1 more 2024-11-21 7.2 HIGH N/A
Heap-based buffer overflow in the Cirrus VGA implementation in (1) KVM before kvm-82 and (2) QEMU on Debian GNU/Linux and Ubuntu might allow local users to gain privileges by using the VNC console for a connection, aka the LGD-54XX "bitblt" heap overflow. NOTE: this issue exists because of an incorrect fix for CVE-2007-1320.
CVE-2008-2382 2 Kvm Qumranet, Qemu 2 Kvm, Qemu 2024-11-21 5.0 MEDIUM N/A
The protocol_client_msg function in vnc.c in the VNC server in (1) Qemu 0.9.1 and earlier and (2) KVM kvm-79 and earlier allows remote attackers to cause a denial of service (infinite loop) via a certain message.
CVE-2008-2004 1 Qemu 1 Qemu 2024-11-21 4.9 MEDIUM N/A
The drive_init function in QEMU 0.9.1 determines the format of a raw disk image based on the header, which allows local guest users to read arbitrary files on the host by modifying the header to identify a different format, which is used when the guest is restarted.
CVE-2008-1945 6 Canonical, Debian, Opensuse and 3 more 9 Ubuntu Linux, Debian Linux, Opensuse and 6 more 2024-11-21 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-2008-0928 1 Qemu 1 Qemu 2024-11-21 4.7 MEDIUM N/A
Qemu 0.9.1 and earlier does not perform range checks for block device read or write requests, which allows guest host users with root privileges to access arbitrary memory and escape the virtual machine.
CVE-2007-6227 1 Qemu 1 Qemu 2024-11-21 7.2 HIGH N/A
QEMU 0.9.0 allows local users of a Windows XP SP2 guest operating system to overwrite the TranslationBlock (code_gen_buffer) buffer, and probably have unspecified other impacts related to an "overflow," via certain Windows executable programs, as demonstrated by qemu-dos.com.
CVE-2007-5730 3 Debian, Qemu, Xen 3 Debian Linux, Qemu, Xen 2024-11-21 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-2007-5729 3 Debian, Opensuse, Qemu 3 Debian Linux, Opensuse, Qemu 2024-11-21 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-2007-1366 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 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-2007-1322 2 Debian, Qemu 2 Debian Linux, Qemu 2024-11-21 2.1 LOW N/A
QEMU 0.8.2 allows local users to halt a virtual machine by executing the icebp instruction.
CVE-2007-1321 4 Debian, Fedoraproject, Qemu and 1 more 5 Debian Linux, Fedora, Fedora Core and 2 more 2024-11-21 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-2007-1320 5 Debian, Fedoraproject, Opensuse and 2 more 6 Debian Linux, Fedora, Fedora Core and 3 more 2024-11-21 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.
