CVE-2015-5278 4 Arista, Canonical, Fedoraproject and 1 more 4 Eos, Ubuntu Linux, Fedora and 1 more 2024-11-21 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.
CVE-2015-5239 5 Arista, Canonical, Fedoraproject and 2 more 8 Eos, Ubuntu Linux, Fedora and 5 more 2024-11-21 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-2014-3471 1 Qemu 1 Qemu 2024-11-21 N/A
Use-after-free vulnerability in hw/pci/pcie.c in QEMU (aka Quick Emulator) allows local guest OS users to cause a denial of service (QEMU instance crash) via hotplug and hotunplug operations of Virtio block devices.
CVE-2014-0148 2 Qemu, Redhat 11 Qemu, Enterprise Linux, Enterprise Linux Desktop and 8 more 2024-11-21 5.5 Medium
Qemu before 2.0 block driver for Hyper-V VHDX Images is vulnerable to infinite loops and other potential issues when calculating BAT entries, due to missing bounds checks for block_size and logical_sector_size variables. These are used to derive other fields like 'sectors_per_block' etc. A user able to alter the Qemu disk image could ise this flaw to crash the Qemu instance resulting in DoS.
CVE-2014-0147 3 Fedoraproject, Qemu, Redhat 12 Fedora, Qemu, Enterprise Linux and 9 more 2024-11-21 6.2 Medium
Qemu before 1.6.2 block diver for the various disk image formats used by Bochs and for the QCOW version 2 format, are vulnerable to a possible crash caused by signed data types or a logic error while creating QCOW2 snapshots, which leads to incorrectly calling update_refcount() routine.
CVE-2014-0146 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-11-21 N/A
The qcow2_open function in the (block/qcow2.c) in QEMU before 1.7.2 and 2.x before 2.0.0 allows local users to cause a denial of service (NULL pointer dereference) via a crafted image which causes an error, related to the initialization of the snapshot_offset and nb_snapshots fields.
CVE-2014-0145 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-11-21 N/A
Multiple buffer overflows in QEMU before 1.7.2 and 2.x before 2.0.0, allow local users to cause a denial of service (crash) or possibly execute arbitrary code via a large (1) L1 table in the qcow2_snapshot_load_tmp in the QCOW 2 block driver (block/qcow2-snapshot.c) or (2) uncompressed chunk, (3) chunk length, or (4) number of sectors in the DMG block driver (block/dmg.c).
CVE-2014-0144 2 Qemu, Redhat 11 Qemu, Enterprise Linux, Enterprise Linux Desktop and 8 more 2024-11-21 8.6 High
QEMU before 2.0.0 block drivers for CLOOP, QCOW2 version 2 and various other image formats are vulnerable to potential memory corruptions, integer/buffer overflows or crash caused by missing input validations which could allow a remote user to execute arbitrary code on the host with the privileges of the QEMU process.
CVE-2014-0143 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-11-21 N/A
Multiple integer overflows in the block drivers in QEMU, possibly before 2.0.0, allow local users to cause a denial of service (crash) via a crafted catalog size in (1) the parallels_open function in block/parallels.c or (2) bochs_open function in bochs.c, a large L1 table in the (3) qcow2_snapshot_load_tmp in qcow2-snapshot.c or (4) qcow2_grow_l1_table function in qcow2-cluster.c, (5) a large request in the bdrv_check_byte_request function in block.c and other block drivers, (6) crafted cluster indexes in the get_refcount function in qcow2-refcount.c, or (7) a large number of blocks in the cloop_open function in cloop.c, which trigger buffer overflows, memory corruption, large memory allocations and out-of-bounds read and writes.
CVE-2014-0142 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-11-21 N/A
QEMU, possibly before 2.0.0, allows local users to cause a denial of service (divide-by-zero error and crash) via a zero value in the (1) tracks field to the seek_to_sector function in block/parallels.c or (2) extent_size field in the bochs function in block/bochs.c.
CVE-2013-4536 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-11-21 7.8 High
An user able to alter the savevm data (either on the disk or over the wire during migration) could use this flaw to to corrupt QEMU process memory on the (destination) host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.
CVE-2013-4535 2 Qemu, Redhat 8 Qemu, Enterprise Linux, Enterprise Linux Desktop and 5 more 2024-11-21 8.8 High
The virtqueue_map_sg function in hw/virtio/virtio.c in QEMU before 1.7.2 allows remote attackers to execute arbitrary files via a crafted savevm image, related to virtio-block or virtio-serial read.
CVE-2013-4532 3 Canonical, Debian, Qemu 3 Ubuntu Linux, Debian Linux, Qemu 2024-11-21 7.8 High
Qemu 1.1.2+dfsg to 2.1+dfsg suffers from a buffer overrun which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.
CVE-2013-2016 3 Debian, Novell, Qemu 4 Debian Linux, Open Desktop Server, Open Enterprise Server and 1 more 2024-11-21 7.8 High
A flaw was found in the way qemu v1.3.0 and later (virtio-rng) validates addresses when guest accesses the config space of a virtio device. If the virtio device has zero/small sized config space, such as virtio-rng, a privileged guest user could use this flaw to access the matching host's qemu address space and thus increase their privileges on the host.
