CWE-400: Uncontrolled Resource Consumption
CWE-611: Improper Restriction of XML External Entity Reference
CWE-138: Improper Neutralization of Special Elements
CWE-121: Stack-based Buffer Overflow
CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')
CWE-835: Loop with Unreachable Exit Condition ('Infinite Loop')
CWE-20: Improper Input Validation
Improper neutralization of special elements in commands ('command injection') in GitHub Copilot and Visual Studio Code allows authorized attackers to disclose information over a network.
CWE-77 - Improper Neutralization of Special Elements used in a Command ('Command Injection')A race condition in the .NET Framework's concurrent execution of shared resources allows unauthorized attackers to cause a denial of service over a network.
Improper input validation in Microsoft PowerShell enables a local unauthorized attacker to bypass security features, potentially compromising system integrity.
Uncontrolled resource consumption vulnerabilities in the .NET framework allow unauthorized attackers to cause denial of service conditions over a network by exhausting system resources.
CWE-611 - Improper Restriction of XML External Entity ReferenceImproper neutralization of special elements in the .NET framework allows unauthorized attackers to conduct network spoofing attacks, compromising network integrity and security.
A stack-based buffer overflow vulnerability in .NET and Visual Studio allows an unauthorized attacker to cause a denial of service over a network.
CWE-121 - Stack-based Buffer OverflowA race condition in the .NET Framework's concurrent execution of shared resources allows unauthorized attackers to cause a denial of service over a network.
CWE-362 - Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition')An infinite loop vulnerability in .NET, .NET Framework, and Visual Studio can be exploited by unauthorized attackers to cause a denial of service over a network.
