CVE-2020-1284 [MEDIUM] Windows SMBv3 Client/Server Denial of Service Vulnerability
Windows SMBv3 Client/Server Denial of Service Vulnerability
Description: A denial of service vulnerability exists in the way that the Microsoft Server Message Block 3.1.1 (SMBv3) protocol handles certain requests. An authenticated attacker who successfully exploited this vulnerability against an SMB Server could cause the affected system to crash. An unauthenticated attacker could also exploit this this vulnerability against an SMB client and cause the affected system to crash.
To exploit the vulnerability against a server, an authenticated attacker could send a specially crafted packet to a targeted SMBv3 server. To exploit the vulnerability against a client, an unauthenticated attacker would need to configure a malicious SMBv3 server and convince a user to connect to it.

CVE-2020-27217 [HIGH] CWE-1284 Improper Validation of Specified Quantity in Input in Eclipse Hono
Improper Validation of Specified Quantity in Input in Eclipse Hono
In Eclipse Hono version 1.3.0 and 1.4.0 the AMQP protocol adapter does not verify the size of AMQP messages received from devices. In particular, a device may send messages that are bigger than the max-message-size that the protocol adapter has indicated during link establishment. While the AMQP 1.0 protocol explicitly disallows a peer to send such messages, a hand crafted AMQP 1.0 client could exploit this behavior in order to send a message of unlimited size to the adapter, eventually causing the adapter to fail with an out of memory exception.
