We take security seriously and provide security updates for the following versions of the Ada Result Library:

Note: As this is a foundational library for error handling and concurrency, we recommend always using the latest stable version to ensure you have the most recent security fixes and improvements.

Please do not report security vulnerabilities through public GitHub issues.

If you discover a security vulnerability in the Ada Result Library, please report it responsibly by following these steps:

Send a detailed report to our security team:

• Email: mjgardner@abitofhelp.com
• Subject: [SECURITY] Ada Result Library - Vulnerability Report
• GitHub: You can also create a private security advisory through GitHub's security tab

Please include the following information in your report:

• Description: A clear description of the vulnerability
• Impact: Potential impact and severity assessment
• Reproduction: Step-by-step instructions to reproduce the issue
• Environment: Ada compiler version, operating system, and library version
• Code Sample: Minimal code example demonstrating the vulnerability (if applicable)
• Suggested Fix: If you have ideas for how to fix the issue (optional)

We are committed to responding to security reports promptly:

• Initial Response: Within 48 hours of receiving your report
• Assessment: Within 5 business days, we'll provide an initial assessment
• Resolution: We aim to resolve critical security issues within 30 days
• Disclosure: Coordinated disclosure after the fix is available

The Ada Result Library is designed with memory safety as a core principle:

• Automatic Memory Management: Uses Ada's controlled types for deterministic cleanup
• RAII Guarantees: Resources are automatically released when objects go out of scope
• No Manual Memory Management: Eliminates common memory-related vulnerabilities
• Deep Copy Semantics: Prevents use-after-free and dangling reference issues

As an async library with concurrency support, we address thread safety concerns:

• Protected Types: Thread-safe operations using Ada's protected types
• Race Condition Prevention: Careful design to prevent data races
• Deadlock Avoidance: Structured concurrency patterns to avoid deadlocks
• Atomic Operations: Where appropriate, using atomic operations for performance

Ada's strong type system provides additional security benefits:

• Compile-Time Checks: Many potential runtime errors caught at compile time
• No Buffer Overflows: Ada's array bounds checking prevents buffer overflows
• Exception Safety: Structured exception handling with guaranteed cleanup
• Contract Programming: Preconditions and postconditions for additional safety

When using this library, be aware of these security considerations:

• Be cautious about error messages that might leak sensitive information
• Consider sanitizing error messages in production environments
• Use the library's error wrapping features to control information exposure

• Monitor memory usage in long-running async operations
• Implement appropriate timeouts for async operations
• Be aware of potential resource leaks in error conditions

• Follow the library's guidelines for thread-safe usage
• Use protected operations when sharing Result objects between tasks
• Be careful with mutable references in concurrent contexts

When using the Ada Result Library:

# Update to the latest version
alr update
alr build

-- Use appropriate compiler flags for maximum safety
pragma Assertion_Policy (Check);
pragma Overflow_Check (Enabled);

-- Always check Result status before unwrapping
if Is_Ok (My_Result) then
   Unwrap_Into (My_Result, Value);
else
   -- Handle error appropriately
   Handle_Error (Get_Error (My_Result));
end if;

-- Avoid exposing sensitive information in error messages
procedure Safe_Operation (Input : String; R : out Result_Type) is
begin
   if not Is_Valid_Input (Input) then
      Make_Err (R, Invalid_Input, "Input validation failed");
      -- Don't include the actual input in the error message
   else
      -- Process input safely
      Process_Input (Input, R);
   end if;
end Safe_Operation;

• We will acknowledge receipt of vulnerability reports within 48 hours
• We will provide regular updates on the progress of fixing reported vulnerabilities
• We will credit security researchers who responsibly disclose vulnerabilities (unless they prefer to remain anonymous)
• We will not pursue legal action against researchers who follow responsible disclosure practices

This security policy applies to:

• The core Ada Result Library code
• Build scripts and configuration files
• Documentation that could impact security
• Examples and test code that demonstrate security-relevant patterns

The following are generally outside the scope of our security policy:

• Issues in third-party dependencies (please report to the respective maintainers)
• Social engineering attacks
• Physical security issues
• Issues requiring physical access to systems

Security updates will be:

• Released as patch versions (e.g., 1.0.1, 1.0.2)
• Documented in the CHANGELOG.md with clear security advisories
• Announced through GitHub releases and security advisories
• Available through Alire package updates

• Primary Contact: Michael Gardner mjgardner@abitofhelp.com
• Organization: A Bit of Help, Inc.
• GitHub: @abitofhelp
• Project Repository: https://github.com/abitofhelp/async-result

We would like to thank the security researchers and community members who help keep the Ada Result Library secure through responsible disclosure of vulnerabilities.

This security policy is effective as of the date of publication and may be updated periodically to reflect changes in our security practices and procedures.
