Description

This security bulletin contains information about 4 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2019-5540)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to information disclosure issue in vmnetdhcp. A remote authenticated attacker can leak memory from the host process and gain unauthorized access to sensitive information on the system.


2) Out-of-bounds write (CVE-ID: CVE-2019-5541)

CWE-ID: CWE-787 - Out-of-bounds write

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a boundary error when processing untrusted input via the e1000e virtual network adapter. A remote administrator can trigger out-of-bounds write and execute arbitrary code on the target system, or create a denial-of-service (DoS) condition on their own VM.


3) Input validation error (CVE-ID: CVE-2019-5542)

CWE-ID: CWE-20 - Improper input validation

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the RPC handler. A remote authenticated attacker can cause a denial-of-service condition on their own VM.


4) Insecure DLL loading (CVE-ID: CVE-2019-5539)

CWE-ID: CWE-427 - Uncontrolled Search Path Element

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the target system.

The vulnerability exists due to insecure loading of a DLL by Cortado Thinprint. A local user can escalate their privileges to administrator on a Windows machine where Workstation or View Agent is installed.
