CVE-2014-0147 3 Fedoraproject, Qemu, Redhat 12 Fedora, Qemu, Enterprise Linux and 9 more 2024-08-06 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-2014-0148 2 Qemu, Redhat 11 Qemu, Enterprise Linux, Enterprise Linux Desktop and 8 more 2024-08-06 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-2014-0144 2 Qemu, Redhat 11 Qemu, Enterprise Linux, Enterprise Linux Desktop and 8 more 2024-08-06 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 2024-08-06 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-2014-0145 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-08-06 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-2014-0142 2 Qemu, Redhat 3 Qemu, Enterprise Linux, Openstack 2024-08-06 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-2015-8818 2 Qemu, Redhat 2 Qemu, Openstack 2024-08-06 5.5 Medium
The cpu_physical_memory_write_rom_internal function in exec.c in QEMU (aka Quick Emulator) does not properly skip MMIO regions, which allows local privileged guest users to cause a denial of service (guest crash) via unspecified vectors.
CVE-2015-8817 2 Qemu, Redhat 2 Qemu, Openstack 2024-08-06 N/A
QEMU (aka Quick Emulator) built to use 'address_space_translate' to map an address to a MemoryRegionSection is vulnerable to an OOB r/w access issue. It could occur while doing pci_dma_read/write calls. Affects QEMU versions >= 1.6.0 and <= 2.3.1. A privileged user inside guest could use this flaw to crash the guest instance resulting in DoS.
CVE-2015-8745 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-06 5.5 Medium
QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It could occur while reading Interrupt Mask Registers (IMR). A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2015-8744 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-06 5.5 Medium
QEMU (aka Quick Emulator) built with a VMWARE VMXNET3 paravirtual NIC emulator support is vulnerable to crash issue. It occurs when a guest sends a Layer-2 packet smaller than 22 bytes. A privileged (CAP_SYS_RAWIO) guest user could use this flaw to crash the QEMU process instance resulting in DoS.
CVE-2015-8743 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-06 7.1 High
QEMU (aka Quick Emulator) built with the NE2000 device emulation support is vulnerable to an OOB r/w access issue. It could occur while performing 'ioport' r/w operations. A privileged (CAP_SYS_RAWIO) user/process could use this flaw to leak or corrupt QEMU memory bytes.
CVE-2015-8701 1 Qemu 1 Qemu 2024-08-06 6.5 Medium
QEMU (aka Quick Emulator) built with the Rocker switch emulation support is vulnerable to an off-by-one error. It happens while processing transmit (tx) descriptors in 'tx_consume' routine, if a descriptor was to have more than allowed (ROCKER_TX_FRAGS_MAX=16) fragments. A privileged user inside guest could use this flaw to cause memory leakage on the host or crash the QEMU process instance resulting in DoS issue.
CVE-2015-8666 2 Debian, Qemu 2 Debian Linux, Qemu 2024-08-06 7.9 High
