Fuzz Harness Build Verification (bf-1ubcb)

Date: 2026-07-06

Summary

Verified that the content fuzz harness is properly configured and builds successfully.

Verification Results

PASS: cargo-fuzz installation

cargo-fuzz 0.13.1

The cargo-fuzz tool is properly installed.

PASS: Content fuzz target exists

The fuzz target is located at fuzz/fuzz_targets/content.rs (not content_fuzzing_targets.rs as mentioned in the task description - this appears to be a naming inconsistency).

Target structure:

  • Tests INV-8 (no panic at public boundary) for content stream interpreter
  • Tests both ProcessingMode::Normal and ProcessingMode::PositionHint
  • Uses proper fuzzer setup with libfuzzer_sys::fuzz_target!
  • Handles all input without panic (safety invariant)

PASS: Fuzz harness builds successfully

cargo fuzz build

Completed without errors. Built binaries:

  • content (59MB) - the main content fuzz target
  • Additional targets: cmap_parser, lexer, object_parser, profile_yaml, stream_decoder, xref

All 7 fuzz targets compiled successfully with no compilation errors.

Acceptance Criteria Status

  • cargo fuzz --version succeeds
  • Content fuzz target file exists (at fuzz/fuzz_targets/content.rs)
  • cargo fuzz build completes without compilation errors
  • No unresolved dependencies or build failures

Notes

The task description referenced content_fuzzing_targets.rs but the actual file is content.rs. This appears to be a documentation discrepancy - the actual fuzz target is properly named and functional.

All fuzz harness infrastructure is working correctly and ready for fuzzing operations.
