1) Out-of-bounds read

EUVDB-ID: #VU28283

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-13253

CWE-ID: CWE-125 - Out-of-bounds read

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary condition in the SD Memory Card emulator while performing block write commands via sdhci_write() in QEMU. A remote user of guest operating system can trigger out-of-bounds read error and crash the QEMU process.

Mitigation

Update the affected package qemu to the latest version.

4) Heap-based buffer overflow

EUVDB-ID: #VU68558

Risk: Medium

CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-17380

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

5) Heap-based buffer overflow

EUVDB-ID: #VU47247

Risk: Medium

CVSSv3.1: 4.4 [CVSS:3.1/AV:L/AC:H/PR:H/UI:N/S:C/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2020-25085

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to a boundary error within the flatview_read_continue in exec.c because hw/sd/sdhci.c mishandles a write operation in the SDHC_BLKSIZE case. A remote attacker can create a specially crafted file, trick the victim into opening it, trigger heap-based buffer overflow and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package qemu to the latest version.

CVE-ID: CVE-2021-3507

CWE-ID: CWE-122 - Heap-based Buffer Overflow

Exploit availability: No

Description

The vulnerability allows a remote user to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the fdctrl_transfer_handler() function in hw/block/fdc.c while processing DMA read data transfers from the floppy drive to the guest system.

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-1050

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a malicious guest to compromise vulnerable system.
