Foxit Reader 9.6.0.25114 and earlier has two unique RecursiveCall bugs involving 3 functions exhausting available stack memory because of Uncontrolled Recursion in the V8 JavaScript engine (issue 2 of 2).

A denial of service vulnerability exists when .NET Core improperly handles web requests, aka '.NET Core Denial of Service Vulnerability'.

A denial of service vulnerability exists when the XmlLite runtime (XmlLite.dll) improperly parses XML input. An attacker who successfully exploited this vulnerability could cause a denial of service against an XML application. A remote unauthenticated attacker could exploit this vulnerability by issuing specially crafted requests to an XML application. The update addresses the vulnerability by correcting how the XmlLite runtime parses XML input.

Windows TCP/IP Driver Denial of Service Vulnerability

A denial of service vulnerability exists in Remote Desktop Protocol (RDP) when an attacker connects to the target system using RDP and sends specially crafted requests. An attacker who successfully exploited this vulnerability could cause the RDP service on the target system to stop responding. To exploit this vulnerability, an attacker would need to run a specially crafted application against a server which provides Remote Desktop Protocol (RDP) services. The update addresses the vulnerability by correcting how RDP handles connection requests.

A memory corruption vulnerability exists in the Windows Server DHCP service when an attacker sends specially crafted packets to a DHCP failover server. An attacker who successfully exploited the vulnerability could cause the DHCP service to become nonresponsive. To exploit the vulnerability, an attacker could send a specially crafted packet to a DHCP server. However, the DHCP server must be set to failover mode for the attack to succeed. The security update addresses the vulnerability by correcting how DHCP failover servers handle network packets.
