Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU78780

Risk: Low

CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-2861

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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

The vulnerability exists due to an error in the 9p passthrough filesystem (9pfs) implementation in QEMU. A local user can escape from the exported 9p tree by creating and opening a device file in the shared folder.

Mitigation

Update the affected package qemu to the latest version.

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

2) Infinite loop

EUVDB-ID: #VU78946

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-2023-3255

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

Exploit availability: No

Description

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

The vulnerability exists due to infinite loop within the vnc_client_cut_text_ext function in ui/vnc-clipboard.c. A remote authenticated client who is able to send a clipboard to the QEMU built-in VNC server can perform a denial of service conditions.

Mitigation

Update the affected package qemu to the latest version.

3) Reachable Assertion

EUVDB-ID: #VU78948

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-2023-3301

CWE-ID: CWE-617 - Reachable Assertion

Exploit availability: No

Description

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

The vulnerability exists due to a reachable assertion. When a peer nic is still attached to the vdpa backend, it is too early to free up the vhost-net and vdpa structures. If these structures are freed here, then QEMU crashes when the guest is being shut down.

Mitigation

Update the affected package qemu to the latest version.
