CVE-2011-1146 1 Redhat 3 Enterprise Linux, Libvirt, Rhel Virtualization 2025-04-11 N/A
libvirt.c in the API in Red Hat libvirt 0.8.8 does not properly restrict operations in a read-only connection, which allows remote attackers to cause a denial of service (host OS crash) or possibly execute arbitrary code via a (1) virNodeDeviceDettach, (2) virNodeDeviceReset, (3) virDomainRevertToSnapshot, (4) virDomainSnapshotDelete, (5) virNodeDeviceReAttach, or (6) virConnectDomainXMLToNative call, a different vulnerability than CVE-2008-5086.
CVE-2012-3515 7 Canonical, Debian, Opensuse and 4 more 15 Ubuntu Linux, Debian Linux, Opensuse and 12 more 2025-04-11 N/A
Qemu, as used in Xen 4.0, 4.1 and possibly other products, when emulating certain devices with a virtual console backend, allows local OS guest users to gain privileges via a crafted escape VT100 sequence that triggers the overwrite of a "device model's address space."
CVE-2012-6075 7 Canonical, Debian, Fedoraproject and 4 more 15 Ubuntu Linux, Debian Linux, Fedora and 12 more 2025-04-11 N/A
Buffer overflow in the e1000_receive function in the e1000 device driver (hw/e1000.c) in QEMU 1.3.0-rc2 and other versions, when the SBP and LPE flags are disabled, allows remote attackers to cause a denial of service (guest OS crash) and possibly execute arbitrary guest code via a large packet.
CVE-2012-2121 2 Linux, Redhat 3 Linux Kernel, Enterprise Linux, Rhel Virtualization 2025-04-11 N/A
The KVM implementation in the Linux kernel before 3.3.4 does not properly manage the relationships between memory slots and the iommu, which allows guest OS users to cause a denial of service (memory leak and host OS crash) by leveraging administrative access to the guest OS to conduct hotunplug and hotplug operations on devices.
CVE-2011-4622 1 Redhat 3 Enterprise Linux, Kvm, Rhel Virtualization 2025-04-11 N/A
The create_pit_timer function in arch/x86/kvm/i8254.c in KVM 83, and possibly other versions, does not properly handle when Programmable Interval Timer (PIT) interrupt requests (IRQs) when a virtual interrupt controller (irqchip) is not available, which allows local users to cause a denial of service (NULL pointer dereference) by starting a timer.
CVE-2011-2511 1 Redhat 3 Enterprise Linux, Libvirt, Rhel Virtualization 2025-04-11 N/A
Integer overflow in libvirt before 0.9.3 allows remote authenticated users to cause a denial of service (libvirtd crash) and possibly execute arbitrary code via a crafted VirDomainGetVcpus RPC call that triggers memory corruption.
CVE-2017-2620 5 Citrix, Debian, Qemu and 2 more 12 Xenserver, Debian Linux, Qemu and 9 more 2024-11-21 N/A
Quick emulator (QEMU) before 2.8 built with the Cirrus CLGD 54xx VGA Emulator support is vulnerable to an out-of-bounds access issue. The issue could occur while copying VGA data in cirrus_bitblt_cputovideo. A privileged user inside guest could use this flaw to crash the QEMU process OR potentially execute arbitrary code on host with privileges of the QEMU process.
CVE-2017-2615 5 Citrix, Debian, Qemu and 2 more 12 Xenserver, Debian Linux, Qemu and 9 more 2024-11-21 N/A
Quick emulator (QEMU) built with the Cirrus CLGD 54xx VGA emulator support is vulnerable to an out-of-bounds access issue. It could occur while copying VGA data via bitblt copy in backward mode. A privileged user inside a guest could use this flaw to crash the QEMU process resulting in DoS or potentially execute arbitrary code on the host with privileges of QEMU process on the host.
