This security bulletin contains information about 2 vulnerabilities.
EUVDB-ID: #VU80016
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2023-3180
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: No
Description The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the virtio_crypto_handle_sym_req() function in hw/virtio/virtio-crypto.c of the QEMU virtual crypto device when handling data encryption/decryption requests. A local user trigger an out-of-bounds write and perform a denial of service 9DoS) attack.
Install updates from vendor's repository.

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
DescriptionThe 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.
MitigationInstall updates from vendor's repository.
