Description
This security bulletin contains information about 1 security vulnerability.
1) Input validation error (CVE-ID: CVE-2020-9005)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack or execute arbitrary code.
The vulnerability exists due to insufficient validation of user-supplied input in the "meshsystem.dll". A remote attacker can create a gaming server, invite a victim to this server, because a crafted map is mishandled during a vulnerable "GetValue" function call and execute arbitrary code or cause a denial of service condition on the target system.
