Security Bulletin
This security bulletin contains information about 9 vulnerabilities.
1) Input validation error
EUVDB-ID: #VU22688
Risk: Low
CVSSv3.1: 6.6 [CVSS:3.1/AV:A/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-1389
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a local user to execute arbitrary code on the target system.
The vulnerability exists due to insufficient validation of user-supplied input when Microsoft Hyper-V Network Switch on a host server does not properly validate input from a privileged user on a guest operating system. An administrator on adjacent network can execute arbitrary code on the target system.
Install updates from vendor's website.
