Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Infinite loop

EUVDB-ID: #VU73788

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-2020-14394

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

Exploit availability: No

Description

The vulnerability allows an attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to infinite loop in the USB xHCI controller emulation of QEMU while computing the length of the Transfer Request Block (TRB) Ring. A privileged user on the guest OS can consume all available system resources and cause denial of service conditions of the QEMU process on the host.

Mitigation

Update the affected package qemu to the latest version.

No. We are not aware of malware exploiting this vulnerability.

2) 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.

3) Use-after-free

EUVDB-ID: #VU64570

Risk: Medium

CVSSv3.1: 7 [CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-3929

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

The vulnerability allows a remote user to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in the NVM Express Controller emulation in QEMU within the dma_buf_write() and dma_buf_read() function in hw/nvme/ctrl.c:nvme_tx(). A remote privileged user on the guest OS can trigger a use-after-free error and execute arbitrary code on 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.

4) 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.

5) Use-after-free

EUVDB-ID: #VU72308

Risk: High

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.

The vulnerability exists due to a use-after-free error in the QEMU implementation of VMWare's paravirtual RDMA device. A specially crafted driver on a malicious guest can execute HW commands when shared buffers are not yet allocated, trigger a use-after-free error and execute arbitrary code on the QEMU host.

Mitigation

Update the affected package qemu to the latest version.
