• Supported Versions
• Reporting Vulnerabilities
• Security Guidelines
• Vulnerability Handling Policy
• Best Practices

This project maintains security updates for the following versions:

If you discover a security vulnerability in this project, please report it responsibly:

1. GitHub Issues (Preferred)

   • Open a new issue at: Security Issues
   • Use the title format: [SECURITY] Brief description
   • Mark the issue as confidential if possible

2. Email (Alternative)

   • Send details to the project maintainer
   • Use subject line: [SECURITY] Compiler Construction Vulnerability Report

When reporting a vulnerability, please provide:

• Description: Clear explanation of the vulnerability
• Impact: What could an attacker do?
• Steps to Reproduce: How to trigger the vulnerability
• Proof of Concept: Code or screenshots demonstrating the issue
• Environment: OS, compiler versions, tools used
• Suggested Fix (optional): If you have recommendations

• Acknowledgment: Within 48 hours
• Investigation: Within 7 days
• Resolution: Within 30 days (depending on severity)
• Public Disclosure: Coordinated with the reporter

When contributing code to this project:

1. Input Validation
   • Always validate user input
   • Use bounds checking for arrays and buffers
   • Sanitize data before processing

// Good: Input validation
int process_token(char *input, int length) {
    if (input == NULL || length <= 0) {
        return ERROR_INVALID_INPUT;
    }
    if (input[length] != '\0') {
        return ERROR_BUFFER_OVERFLOW;
    }
    // Process safely
    return SUCCESS;
}

2. Memory Management
   • Free allocated memory
   • Avoid buffer overflows
   • Use safe string functions

// Good: Safe memory handling
char *buffer = malloc(size);
if (buffer == NULL) {
    fprintf(stderr, "Memory allocation failed\n");
    return EXIT_FAILURE;
}
// Use buffer...
free(buffer);
buffer = NULL;

3. Avoid Common Vulnerabilities
   • No hardcoded passwords or secrets
   • No command injection vulnerabilities
   • No use of unsafe functions (strcpy, sprintf)

When using this project:

1. Download from Official Source

   • Only clone from the official repository
   • Verify the repository URL: https://github.com/H0NEYP0T-466/Compiler_Construction.git

2. Review Code Before Running

   • Especially when running generated executables
   • Check for malicious modifications

3. Run in Safe Environment

   • Use virtual machines for testing unknown code
   • Avoid running with administrator privileges

We classify vulnerabilities by severity:

1. Triage

   • Validate the vulnerability
   • Assess severity and impact
   • Assign to appropriate team member

2. Fix Development

   • Create a patch or workaround
   • Test the fix thoroughly
   • Document the changes

3. Release

   • Deploy the fix
   • Update affected versions
   • Notify users if necessary

4. Disclosure

   • Credit the reporter (with permission)
   • Publish security advisory
   • Update documentation

• Reporter: Kept informed throughout the process
• Users: Notified of critical vulnerabilities
• Public: Security advisories published after fix

When reviewing code, check for:

• Input validation on all user inputs
• Proper memory management (malloc/free)
• No buffer overflows
• No format string vulnerabilities
• No command injection risks
• Proper error handling
• No hardcoded secrets
• Secure file operations

1. Design: Consider security in architecture
2. Implement: Follow secure coding practices
3. Test: Include security testing
4. Review: Peer review for security issues
5. Deploy: Secure deployment practices
6. Monitor: Watch for vulnerabilities

• OWASP Top 10
• CWE Top 25
• NIST Vulnerability Database
