Security Bulletin
This security bulletin contains information about 6 vulnerabilities.
EUVDB-ID: #VU63778
Risk: Low
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3682
CWE-ID:
CWE-763 - Release of invalid pointer or reference
Exploit availability: No
DescriptionThe vulnerability allows a remote user to escalate privileges on the system.
The vulnerability exists in the USB redirector device emulation of QEMU when dropping packets during a bulk transfer from a SPICE client. A remote user can make QEMU call free() with faked heap chunk metadata to perform a denial of service or escalate privileges on the system.
MitigationInstall update from vendor's website.

EUVDB-ID: #VU58812
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2021-3930
CWE-ID:
CWE-193 - Off-by-one Error
Exploit availability: No
DescriptionThe vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to an off-by-one error in the SCSI device emulation in QEMU. A remote user on the guest OS can can trigger an off-by-one error while processing MODE SELECT commands in mode_sense_page() if the 'page' argument is set to MODE_PAGE_ALLS (0x3f). Successful exploitation of the vulnerability may result in QEMU crash.

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
DescriptionThe 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.
