1) Out-of-bounds write
EUVDB-ID: #VU45985
Risk: Medium
CVSSv4.0: 7.3 [CVSS:4.0/AV:A/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P/U:Green]
CVE-ID: CVE-2020-14364
CWE-ID:
CWE-787 - Out-of-bounds write
Exploit availability: Yes
DescriptionThe vulnerability allows a remote user to compromise vulnerable system.
The vulnerability exists due to a boundary error within the USB emulator in QEMU. A remote user with access to guest operating system on the guest operating system can send specially crafted USB packets, trigger out-of-bounds write and execute arbitrary code on the host system.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
