openEuler 20.03 LTS SP1 update for qemu
Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) 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.
MitigationInstall updates from vendor's repository.

Q & A
Can this vulnerability be exploited remotely?
No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Double free
EUVDB-ID: #VU89047
Risk: Low
CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-3446
CWE-ID:
CWE-415 - Double Free
Exploit availability: No
DescriptionThe vulnerability allows a malicious guest to escalate privileges on the system.
The vulnerability exists due to a boundary error in QEMU virtio devices (virtio-gpu, virtio-serial-bus, virtio-crypto), where the mem_reentrancy_guard flag insufficiently protects against DMA reentrancy issues. A malicious guest can trigger a double free error and execute arbitrary code within the context of the QEMU process on the host.

3) Heap-based buffer overflow
EUVDB-ID: #VU89048
Risk: Low
CVSSv3.1: 5.3 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2024-3447
CWE-ID:
CWE-122 - Heap-based Buffer Overflow
Exploit availability: No
DescriptionThe vulnerability allows a malicious guest to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error in the SDHCI device emulation. A malicious guest can set both "s->data_count" and the size of "s->fifo_buffer" to the value of "0x200" to trigger an out-of-bound memory access and perform a denial of service (DoS) attack.
