Foxit PDF Reader before 12.0.1 and PDF Editor before 12.0.1 allow an exportXFAData NULL pointer dereference.

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 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 denial of service vulnerability exists in Microsoft Exchange Server software when the software fails to properly handle objects in memory, aka 'Microsoft Exchange Denial of Service Vulnerability'.

A denial of service vulnerability exists when Microsoft Defender improperly handles files, aka 'Microsoft Defender Denial of Service Vulnerability'.

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.

A Denial-of-Service (DoS) vulnerability was discovered in F-Secure Atlant and in certain WithSecure products whereby the scanning the aeheur.dll component can crash the scanning engine. The exploit can be triggered remotely by an attacker.

Multiple Denial-of-Service (DoS) vulnerability was discovered in F-Secure & WithSecure products whereby the aerdl.dll unpacker handler function crashes. This can lead to a possible scanning engine crash.

An out-of-bounds read vulnerability in the TeamViewer DEX Client (former 1E Client) - Content Distribution Service (NomadBranch.exe) prior version 26.1 for Windows allows a remote attacker to leak stack memory and cause a denial of service via a crafted request. The leaked stack memory could be used to bypass ASLR remotely and facilitate exploitation of other vulnerabilities on the affected system.

Null pointer dereference in Windows Local Security Authority Subsystem Service (LSASS) allows an unauthorized attacker to deny service over a network.

Microsoft WS-Discovery Denial of Service Vulnerability

Windows Standards-Based Storage Management Service Denial of Service Vulnerability

.NET and Visual Studio Denial of Service Vulnerability

A denial of service vulnerability exists when System.IO.Pipelines improperly handles requests, aka "System.IO.Pipelines Denial of Service." This affects .NET Core 2.1, System.IO.Pipelines, ASP.NET Core 2.1.

Buffer over-read in Windows GDI+ allows an unauthorized attacker to deny service over a network.

Windows Network Address Translation (NAT) Denial of Service Vulnerability

Windows Secure Channel Denial of Service Vulnerability

A message out-of-bounds read vulnerability in Trend Micro Apex Central could allow a remote attacker to create a denial-of-service condition on affected installations. Please note: authentication is not required in order to exploit this vulnerability.

The GIF parser in ateimg32.dll in AOL Instant Messenger (AIM) 5.9.3797 and earlier allows remote attackers to cause a denial of service (crash) via a malformed buddy icon that causes an integer underflow in a loop counter variable.

A message unchecked NULL return value vulnerability in Trend Micro Apex Central could allow a remote attacker to create a denial-of-service condition on affected installations. Please note: authentication is not required in order to exploit this vulnerability..

Windows Lightweight Directory Access Protocol (LDAP) Denial of Service Vulnerability

zlib before 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches.

The Negotiate Security Software Provider (SSP) interface in Windows 2000, Windows XP, and Windows Server 2003, allows remote attackers to cause a denial of service (crash from null dereference) or execute arbitrary code via a crafted SPNEGO NegTokenInit request during authentication protocol selection.

Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.

Certain WithSecure products allow a Denial of Service because there is an unpack handler crash that can lead to a scanning engine crash. This affects WithSecure Client Security 15, WithSecure Server Security 15, WithSecure Email and Server Security 15, WithSecure Elements Endpoint Protection 17 and later, WithSecure Client Security for Mac 15, WithSecure Elements Endpoint Protection for Mac 17 and later, WithSecure Linux Security 64 12.0, WithSecure Linux Protection 12.0, and WithSecure Atlant 1.0.35-1.

Out-of-bounds read in Windows Internet Information Services allows an unauthorized attacker to deny service over a network.

Windows Standards-Based Storage Management Service Denial of Service Vulnerability
