SUSE update for qemu

1) 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.
