Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Out-of-bounds write

EUVDB-ID: #VU72306

Risk: Medium

CVSSv3.1: 4.9 [CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-3638

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

The vulnerability allows a malicious guest to perform a denial of service (DoS) attack.

The vulnerability exists due to a boundary error in the ATI VGA device emulation of QEMU within the ati_2d_blt() routine while handling MMIO write operations. A malicious guest can crash the QEMU process on the host.

Mitigation

Update the affected package qemu to the latest version.

2) Out-of-bounds write

EUVDB-ID: #VU80016

Risk: Low

CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3180

CWE-ID: CWE-787 - Out-of-bounds write

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within the virtio_crypto_handle_sym_req() function in hw/virtio/virtio-crypto.c of the QEMU virtual crypto device when handling data encryption/decryption requests. A local user trigger an out-of-bounds write and perform a denial of service 9DoS) attack.

Mitigation

Update the affected package qemu to the latest version.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

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

3) NULL pointer dereference

EUVDB-ID: #VU80015

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-3354

CWE-ID: CWE-476 - NULL Pointer Dereference

Exploit availability: No

Description

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

The vulnerability exists due to a NULL pointer dereference error in the QEMU built-in VNC server. When a client connects to the VNC server, QEMU checks whether the current number of connections crosses a certain threshold and if so, cleans up the previous connection. If the previous connection happens to be in the handshake phase and fails, QEMU cleans up the connection again, resulting in NULL pointer dereference and denial of service.

Mitigation

Update the affected package qemu to the latest version.
