CVE-2020-17380

CVE-2020-17380 (QEMU SDHCI) affects QEMU up to 5.0.0 in the SDHCI device emulation (hw/sd/sdhci.c). The flaw is a heap-based buffer overflow that can occur during a multi-block SDMA transfer in sdhci_sdma_transfer_multi_blocks(). A guest user or process could crash the QEMU host process or, poten...

Denial Of Service (DoS)

qemu is vulnerable to denial of service. The vulnerability exists through heap buffer overflow in sdhcisdmatransfermultiblocks in hw/sd/sdhci.c which allows an attacker to cause an application crash...

Arbitrary Code Execution

qemu is vulnerable to arbitrary code execution. The vulnerability exists through a out-of-bounds read/write access flaw in the SDHCI Controller emulator of QEMU,hw/sd/sdhci.c which allows an attacker to cause QEMU to crash or possibly execute arbitrary code on the host...

Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS : QEMU vulnerabilities (USN-4650-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4650-1 advisory. Alexander Bulekov discovered that QEMU incorrectly handled SDHCI device emulation. An attacker inside the guest could use this...

USN-4650-1 qemu vulnerabilities

Alexander Bulekov discovered that QEMU incorrectly handled SDHCI device emulation. An attacker inside the guest could use this issue to cause QEMU to crash, resulting in a denial of service, or possibly execute arbitrary code on the host. In the default installation, when QEMU is used with libvir...

QEMU heap buffer overflow vulnerability (CNVD-2020-54916)

QEMU is a set of simulation processors written by Fabrice Bellard and distributed with source code under the GPL license, widely used on the GNU/Linux platform. A security vulnerability exists in QEMU, which originates in hw/sd/sdhci.c that triggers a memory corruption, which triggers a denial of...

DEBIAN-CVE-2020-25085

QEMU 5.0.0 has a heap-based Buffer Overflow in flatviewreadcontinue in exec.c because hw/sd/sdhci.c mishandles a write operation in the SDHCBLKSIZE case...

Privilege Escalation

qemu:xenial is vulnerable to privilege escalation. The sdhcisdmatransfermultiblocks function in hw/sd/sdhci.c in QEMU aka Quick Emulator allows local OS guest privileged users to cause a denial of service infinite loop and QEMU process crash via vectors involving the transfer mode register during...

CVE-2020-25085

A flaw was found in QEMU. An out-of-bounds read/write access issue was found in the SDHCI Controller emulator of QEMU. It may occur while doing multi block SDMA, if transfer block size exceeds the 's-fifobuffers-bufmaxsz' size which would leave the current element pointer 's-datacount' pointing o...
