We take security seriously and will address security vulnerabilities in the following versions:

We appreciate responsible disclosure of security vulnerabilities. Please do not report security vulnerabilities through public GitHub issues.

1. Email: Send details to [INSERT SECURITY EMAIL HERE]

   • Use subject line: [SECURITY] Brief description
   • Include "SECURITY" in subject for priority handling

2. What to Include:

   • Type of vulnerability (e.g., buffer overflow, SQL injection, XSS)
   • Full paths of source file(s) related to the vulnerability
   • Location of the affected source code (tag/branch/commit or direct URL)
   • Step-by-step instructions to reproduce the issue
   • Proof-of-concept or exploit code (if possible)
   • Impact of the issue, including how an attacker might exploit it

3. Response Timeline:

   • Initial response: Within 48 hours
   • Status update: Within 7 days
   • Resolution target: 30-90 days depending on severity

After you submit a report, the project maintainers will:

1. Acknowledge receipt of your vulnerability report
2. Assess the vulnerability and determine its impact
3. Develop a fix in a private repository
4. Test the fix thoroughly
5. Release a security update
6. Credit you in the security advisory (if desired)

1. Critical vulnerabilities: Released as soon as possible
2. High severity: Bundled in next patch release
3. Medium/Low severity: Included in next minor release

• We follow responsible disclosure
• Please allow us to patch the vulnerability before public disclosure
• We aim for 30-90 days before public disclosure
• We will coordinate disclosure timing with you

1. Keep Updated:

   • Always use the latest stable version
   • Subscribe to release notifications
   • Apply security patches promptly

2. Secure Configuration:

   • Run with minimal required permissions
   • Validate input files before processing
   • Use read-only mounts when possible in containers

3. Input Validation:

   • Verify mesh input files from untrusted sources
   • Check XML files for malicious content
   • Validate file sizes before loading

1. Code Review:

   • All PRs require review before merge
   • Security-sensitive changes need extra scrutiny
   • Use static analysis tools (make lint)

2. Dependencies:

   • Keep dependencies up to date
   • Review security advisories for GTKmm, Boost, GSL, PLplot
   • Use containers with verified base images

3. Memory Safety:

   • Run Valgrind regularly (make valgrind)
   • Check for buffer overflows
   • Validate array bounds
   • Use RAII for resource management

4. File Handling:

   • Validate file paths (no path traversal)
   • Check file permissions
   • Handle errors gracefully
   • Close files properly

• XML file parsing uses Boost.Serialization
• Large mesh files may cause memory exhaustion
• File path validation needed for user inputs

• C++ manual memory management
• Use smart pointers where possible
• Check for memory leaks with Valgrind

This project depends on several third-party libraries:

• GTKmm (LGPL) - UI framework
• Boost (Boost License) - Serialization, algorithms
• GSL (GPL) - Scientific computations
• PLplot (LGPL) - Plotting library

Monitor these projects for security updates.

We use the following tools to maintain security:

• clang-tidy: Static analysis for C++ code
• Valgrind: Memory leak and error detection
• AddressSanitizer: Runtime memory error detection (optional)
• UndefinedBehaviorSanitizer: Undefined behavior detection (optional)

Enable sanitizers during development:

cmake -S . -B build -DENABLE_SANITIZERS=ON
cmake --build build

• Primary: [INSERT EMAIL]
• Backup: [INSERT EMAIL]
• PGP Key: [INSERT PGP KEY ID if applicable]

We currently do not offer a bug bounty program, but we deeply appreciate security research and responsible disclosure. Contributors who report valid security issues will be:

• Publicly credited (if desired)
• Mentioned in release notes
• Listed in CONTRIBUTORS.md

Published security advisories will be available at:

• GitHub Security Advisories
• Release notes in CHANGELOG.md
• Project README.md

By reporting security vulnerabilities, you agree:

• To give us reasonable time to address issues
• Not to exploit vulnerabilities beyond demonstration
• Not to publicly disclose until coordinated release
• To act in good faith

We commit to:

• Acknowledge and respond promptly
• Keep you informed of progress
• Credit you appropriately (if desired)
• Not take legal action against good-faith researchers

• OWASP Secure Coding Practices
• CWE - Common Weakness Enumeration
• CVE - Common Vulnerabilities and Exposures
• NIST National Vulnerability Database
