Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) 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.

The vulnerability exists due to a boundary error in the SDHCI device emulation support while performing a multi block SDMA transfer via the sdhci_sdma_transfer_multi_blocks() routine in hw/sd/sdhci.c. A remote user of the guest OS can trigger a heap-based buffer overflow and crash the QEMU process on the host OS.

Mitigation

Update the affected package qemu to the latest version.

2) 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.

4) Heap-based buffer overflow

EUVDB-ID: #VU64569

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

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. A remote privileged user on the guest OS can trigger a heap-based buffer overflow and crash the QEMU process on the host OS.

Mitigation

Update the affected package qemu to the latest version.

CVE-ID: CVE-2021-4206

CWE-ID: CWE-190 - Integer overflow

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the target system.

The vulnerability exists due to integer overflow in the cursor_alloc() function in the QXL display device emulation in QEMU. A privileged user can crash the QEMU process on the host or potentially execute arbitrary code within the context of the QEMU process.

Mitigation

Update the affected package qemu to the latest version.

7) Use-after-free

EUVDB-ID: #VU68551

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-2022-0216

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error in the LSI53C895A SCSI Host Bus Adapter emulation of QEMU when processing repeated messages to cancel the current SCSI request via the lsi_do_msgout() function. A remote user on the guest OS can trigger a use-after-free error and perform a denial of service attack against the QEMU host.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

Update the affected package qemu to the latest version.
