2) Out-of-bounds write

EUVDB-ID: #VU77499

Risk: Low

CVSSv3.1: 5.8 [CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2023-0330

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

Exploit availability: No

Description

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

The vulnerability exists due to a boundary error within hw/scsi/lsi53c895a.c in QEMU caused by a DMA-MMIO reentrancy problem. A local privileged user can trigger an out-of-bounds write and execute arbitrary code on the target system.

Mitigation

Update the affected package qemu to the latest version.

3) 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.
