This document outlines the security testing setup for videre to ensure the Go version is secure and robust.

The security testing suite includes:

• AFL Fuzzing - Automated vulnerability discovery
• Static Analysis - Code quality and security scanning
• Memory Error Detection - Runtime memory safety checks
• Security Test Suite - Targeted security tests

• Local host integrity is assumed (no active local compromise).
• The runtime environment and PATH are treated as trusted.
• External helper commands (git, wl-copy, wl-paste, xclip) are resolved via PATH by design.
• If an attacker can replace binaries in trusted lookup paths, that is considered host compromise and out of scope for Videre hardening.

# Run all security tests
go test ./...

# Run race detector checks
go test -race ./...

# Run static analysis
go vet ./...
staticcheck ./...

mkdir -p fuzz/input fuzz/output

This creates:

• fuzz/input/ - Seed files for fuzzing
• fuzz/output/ - AFL output directory
• Various malicious seed files

# Single-core fuzzing
afl-fuzz -i fuzz/input -o fuzz/output -- ./fuzz/fuzz_target

# Multi-core parallel fuzzing
afl-fuzz -i fuzz/input -o fuzz/output -M fuzzer01 -- ./fuzz/fuzz_target
afl-fuzz -i fuzz/input -o fuzz/output -S fuzzer02 -- ./fuzz/fuzz_target

# View fuzzing statistics
afl-whatsup fuzz/output/

# Inspect crashes
ls -1 fuzz/output/default/crashes/

The fuzzing includes various attack vectors:

• Text files - Normal content, long lines, empty files
• Binary files - Null bytes, high ASCII, shellcode patterns
• Escape sequences - ANSI escape sequences
• Buffer overflow patterns - Long strings, heap patterns

The tests/security_tests.c includes tests for:

• Buffer overflows - Long strings and heap patterns
• Format string attacks - Malicious format strings
• Integer overflows - Boundary conditions
• Memory exhaustion - Large allocation handling
• File operations - Malicious file content

go test ./...

go vet ./...

staticcheck ./...

Go's built-in race detector can be used to find data races:

go test -race ./...

Add to your CI pipeline:

security:
  script:
    - go test ./...
    - go test -race ./...
    - go vet ./...
    - staticcheck ./...
  artifacts:
    reports:
      junit: security-results.xml

Go is a memory-safe language, which automatically handles memory management and prevents common issues like:

• Buffer overflows - Handled by runtime bounds checking
• Use-after-free - Prevented by garbage collection
• Double free - Prevented by garbage collection
• Memory leaks - Managed by garbage collection

• Integer overflows - Arithmetic operations
• Signed/unsigned issues - Type conversion
• Boundary conditions - Edge cases

• Format strings - Printf vulnerabilities
• Path traversal - File operations
• Command injection - System calls

• Escape sequences - Terminal codes
• ANSI codes - Color/formatting
• Unicode handling - Text encoding

• File loading - editorOpen()
• Text insertion - editorInsertChar()
• Row operations - editorInsertRow(), editorDelRow()
• Search functionality - Pattern matching
• Syntax highlighting - File parsing

• File I/O - All file operations
• Memory allocation - Dynamic memory management
• String operations - Text processing
• Terminal handling - Escape sequence parsing

When AFL finds crashes:

# Analyze crash
gdb -ex 'run' -ex 'bt' -- fuzz/fuzz_target < fuzz/output/default/crashes/id:000000*

# Minimize crash case
afl-tmin -i fuzz/output/default/crashes/id:000000* -o minimized_crash -- fuzz/fuzz_target

• All bounds checks validated
• Input sanitization implemented
• Memory allocation checked
• String operations safe
• File operations validated

• Use safe string functions (strncpy, snprintf)
• Validate all input bounds
• Check return values of system calls
• Initialize all variables
• Use RAII patterns for memory management

If you find a security vulnerability:

1. Do not open a public issue
2. Email: security@videre.dev
3. Include: reproduction steps, impact assessment
4. Allow 90 days before disclosure

This security testing helps ensure compliance with:

• CWE Top 25 - Common weakness enumeration
• OWASP - Web application security
• ISO 27001 - Information security management
• SOC 2 - Security controls

Security testing adds minimal overhead:

• Sanitizers: ~2x slowdown
• Static analysis: Build time increase
• Fuzzing: Continuous background process
