dotnet: .NET Framework: Denial of Service via improper input validation

A flaw was found in .NET Framework. This improper validation of input allows an unauthorized attacker to remotely deny service over a network. This vulnerability can lead to a Denial of Service DoS condition, making the affected system unavailable to legitimate users...

dotnet: .NET: Security feature bypass due to incorrect authorization

A flaw was found in .NET where incorrect authorization allows an unauthorized attacker to bypass a security feature over a network. This vulnerability enables an attacker to circumvent intended security controls, potentially leading to unauthorized access or actions within the affected system...

dotnet: .NET: Local code execution via deserialization of untrusted data

A flaw was found in .NET. This vulnerability allows an unauthorized attacker to execute code locally by exploiting a deserialization of untrusted data. This means that if an attacker can provide specially crafted data, the .NET application may process it in a way that leads to the execution of...

dotnet: .NET Core: Denial of Service via type confusion

A flaw was found in .NET Core. This vulnerability, known as type confusion, allows an unauthorized remote attacker to cause a denial of service DoS over a network. By exploiting this flaw, an attacker can make the affected system unavailable to legitimate users...

dotnet: .NET: Denial of Service vulnerability due to uncontrolled resource allocation

A flaw was found in .NET where uncontrolled resource allocation can be exploited by an unauthorized attacker over a network. This vulnerability allows the attacker to exhaust available resources, leading to a Denial of Service DoS condition. The lack of limits or throttling mechanisms enables an...

dotnet: .NET: Denial of Service due to uncontrolled resource allocation

A flaw was found in .NET where uncontrolled allocation of resources can lead to a Denial of Service DoS. An unauthorized remote attacker could exploit this vulnerability by continuously requesting resources without limits or throttling, causing the affected system to become unresponsive or crash...

dotnet: .NET Framework: Denial of Service via network-based buffer overflow

A flaw was found in .NET Framework. This vulnerability, a stack-based buffer overflow, allows an unauthorized attacker to remotely exploit the system over a network. Successful exploitation can lead to a denial of service DoS, making the affected system unavailable to legitimate users...

dotnet: .NET Framework: Remote Denial of Service due to uncontrolled resource allocation

A flaw was found in .NET Framework. An unauthorized attacker can exploit this vulnerability remotely by causing the system to allocate resources without proper limits or throttling. This uncontrolled resource allocation can lead to a Denial of Service DoS, making the affected system unresponsive ...

dotnet: .NET: Local tampering via improper link resolution

A flaw was found in .NET. This vulnerability, stemming from improper link resolution before file access, allows an authorized local attacker to perform tampering. This could lead to unauthorized modification of data or system files...

dotnet: .NET Framework: Local Code Execution via Protection Mechanism Failure

A flaw was found in .NET Framework. This protection mechanism failure allows an unauthorized attacker to execute arbitrary code locally. Successful exploitation of this vulnerability can lead to a complete compromise of the affected system...
