Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) 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.

2) Integer underflow

EUVDB-ID: #VU72307

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3165

CWE-ID: CWE-191 - Integer underflow

Exploit availability: No

Description

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

The vulnerability exists due to integer underflow in the QEMU VNC server while processing ClientCutText messages in the extended format. A remote client can send a specially crafted payload message to the VNC server and perform a denial of service (DoS) attack.

Mitigation

Update the affected package qemu to the latest version.

3) Out-of-bounds read

EUVDB-ID: #VU71136

Risk: Medium

CVSSv3.1: 5.5 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-4144

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary condition within the qxl_phys2virt() function in the QXL display device emulation in QEMU. A malicious guest user can trigger an out-of-bounds read error and crash the QEMU process on the host

Mitigation

Update the affected package qemu to the latest version.
