Version Confirmation + +- **Source**: `DesktopEditor/xml/libxml2/NEWS` line 13: `2.9.2: Oct 16 2014` +- **Age**: ~11.5 years old at time of audit +- **Files**: 101 `.c` files, 69 `.h` files + +--- + +## 2. Source Code Modifications + +### 2.1 `xmlversion.h` — Template Placeholders + +**File**: `DesktopEditor/xml/libxml2/include/libxml/xmlversion.h` + +This file has been modified from upstream to use build-time template substitution: + +| Line | Placeholder | Purpose | +|------|------------|---------| +| 32 | `#define LIBXML_DOTTED_VERSION "1.2.3"` | Generic placeholder version string | +| 40 | `#define LIBXML_VERSION_NUMBER LIBXML_DOTTED_VERSION` | Version as string (not numeric) | +| 50 | `#define LIBXML_VERSION_STRING "@LIBXML_VERSION_NUMBER@"` | CMake template placeholder | +| 57 | `#define LIBXML_VERSION_EXTRA "@LIBXML_VERSION_EXTRA@"` | CMake template placeholder | +| 395 | `#define LIBXML_MODULE_EXTENSION "@MODULE_EXTENSION@"` | CMake template placeholder | + +**Impact**: In standard libxml2, `LIBXML_DOTTED_VERSION` would be `"2.9.2"` and `LIBXML_VERSION` would be the numeric `20902`. Here, `LIBXML_VERSION` is the string `"1.2.3"` which means any `xmlCheckVersion()` comparison will fail or behave unexpectedly. The ONLYOFFICE code never calls `LIBXML_TEST_VERSION` or `xmlCheckVersion()`, so this is not a runtime issue, but it's a code smell. + +**Key change from upstream**: The `#ifndef LIBXML_VERSION_NUMBER` guard (line 39) was added to allow the build system to override the version externally. This is NOT standard upstream behavior. + +### 2.2 `error.c` — XML_ERROR_DISABLE_MODE Patch + +**File**: `DesktopEditor/xml/libxml2/error.c`, lines 71-88 + +```c +#ifndef XML_ERROR_DISABLE_MODE +void XMLCDECL +xmlGenericErrorDefaultFunc(void *ctx ATTRIBUTE_UNUSED, const char *msg, ...) { + va_list args; + if (xmlGenericErrorContext == NULL) + xmlGenericErrorContext = (void *) stderr; + va_start(args, msg); + vfprintf((FILE *)xmlGenericErrorContext, msg, args); + va_end(args); +} +#else +void XMLCDECL +xmlGenericErrorDefaultFunc(void *ctx ATTRIBUTE_UNUSED, const char *msg, ...) { + // NONE +} +#endif +``` + +**Purpose**: In release builds, `XML_ERROR_DISABLE_MODE` is defined, which makes the default error handler a no-op. This suppresses all XML parsing error output to stderr in production. + +**Risk on update**: This is a single, well-contained modification. Easy to re-apply to a new version. However, the error.c file in libxml2 2.12.x has been significantly restructured, so the patch location may shift. + +### 2.3 No Other Source Modifications Detected + +The remaining 100 `.c` and 68 `.h` files in `libxml2/` contain: +- No ONLYOFFICE/Ascensio copyright strings +- No ONLYOFFICE-specific `#ifdef` blocks +- No custom IO callbacks registered +- No custom entity loaders + +**Conclusion**: The libxml2 source is essentially unmodified upstream 2.9.2 with exactly 2 customizations: +1.

Risk Assessment for Updating to 2.12.x + +### 7.1 HIGH Risk Items + +1. **API Breaking Changes**: libxml2 2.12.x has significant API changes: + - `LIBXML_SAX1_ENABLED` is **deprecated** and may be removed + - `xmlSAXHandler` structure has changed + - Many functions have stricter const-correctness + - Thread-safety model changed (global state removed) + - `xmlInitParser()` / `xmlCleanupParser()` behavior changed + +2. **xmlversion.h Template System**: The ONLYOFFICE version templating approach (`"1.2.3"` as `LIBXML_DOTTED_VERSION`) is fragile. In 2.12.x, `LIBXML_VERSION` must be a numeric value for version checks to work correctly. + +3. **C14N API Changes**: `xmlC14NExecute()` signature may have changed. The `NSXmlCanonicalizator::Execute()` in `xmldom.cpp` directly calls this API. + +4. **XMLReader API**: The `xmlTextReader*` APIs are the core dependency. While still present in 2.12.x, behavior around error handling and entity expansion has changed. + +### 7.2 MEDIUM Risk Items + +5. **Error Handling**: `XML_ERROR_DISABLE_MODE` patch location may shift in the restructured error.c. Easy to re-apply but needs verification. + +6. **Build System**: The custom config.h files (qt/config.h, vs2013/config.h) may need updates for new platform requirements in 2.12.x. + +7. **Unity Build Split**: `libxml2_all.c` / `libxml2_all2.c` may need regeneration as source file lists change in 2.12.x. + +8. **Symbol Visibility**: `xmlexports.h` is unmodified but the 2.12.x version has a different export model. The `LIBXML_STATIC` define should handle this but needs testing. + +### 7.3 LOW Risk Items + +9. **Wrapper Code**: The ONLYOFFICE CXmlLiteReader/CXmlNode wrappers are thin and well-abstracted. If the underlying libxml2 APIs are compatible, the wrappers should work without changes. + +10. **Dead Defines**: `_USE_LIBXML2_READER_` is never checked in code. It can be cleaned up during the update. + +--- + +## 8. Recommended Update Strategy + +### Phase 1: Preparation +1. **Generate diff** between ONLYOFFICE's xmlversion.h and error.c vs upstream 2.9.2 to confirm the exact modifications +2. **Test `XML_ERROR_DISABLE_MODE`** equivalent in 2.12.x (check if `xmlSetGenericErrorFunc(NULL, NULL)` is sufficient) +3. **Audit C14N API** compatibility in 2.12.x +4. **Review `LIBXML_SAX1_ENABLED`** deprecation impact + +### Phase 2: Implementation +1. **Drop-in replacement**: Replace `DesktopEditor/xml/libxml2/` with 2.12.x source +2. **Re-apply error.c patch**: Wrap `xmlGenericErrorDefaultFunc` with `XML_ERROR_DISABLE_MODE` guard +3. **Fix xmlversion.h**: Either: + - Use proper upstream `xmlversion.h` with actual version numbers + - OR keep template approach but fix `LIBXML_VERSION` to be numeric +4. **Update source file list**: Update CMakeLists.txt, .pri, .vcxproj with new/removed files +5. **Update unity build files**: Regenerate `libxml2_all.c` / `libxml2_all2.c` +6. **Update config.h files**: Adjust platform detection for 2.12.x requirements +7. **Remove `LIBXML_SAX1_ENABLED`**: If deprecated in 2.12.x, test without it + +### Phase 3: Verification +1. Build all targets: Linux (CMake), Windows (VS), macOS (Xcode), JS/WASM +2. Run existing XML tests +3. Test OOXML parsing (docx, xlsx, pptx) +4. Test ODF parsing +5. Test XML canonicalization (digital signatures) +6. Verify error suppression works in release builds + +--- + +## 9.

codebase at /opt/git/core. + +### Interview Summary +**Key Discussions**: +- Codebase is C++17 document conversion engine (NOT a web app) — security/optimization patterns differ from web applications +- User chose: BOTH security AND performance fixes + test infrastructure +- Vendored libraries: YES — update zlib, OpenJPEG, libxml2 +- Third-party code: NO — leave LeptonLib/OpenJPEG vendored issues as-is +- Large file splits: YES — split project files over 5K lines +- Test infrastructure: YES — ASAN/UBSAN, coverage, expanded CI + +**Research Findings**: +- SSL verification completely disabled on Linux (HIGH) +- ~1,148 std::map instances across ~310 files (not "20+" as initially estimated) +- libxml2 is 2.9.2 from 2014, heavily customized fork +- OpenSSL 1.1.1f is EOL (flagged but explicitly out of scope) +- Zero test coverage infrastructure, no ASAN/UBSAN, no fuzzing +- Three separate copies of zlib in the tree + +### Metis Review +**Identified Gaps** (addressed): +- std::map scale massively underestimated (1,148 vs "20+") → Plan targets ~20 hot-path files, rest deferred +- SHA1/MD5 in OOXML/ODF encryption is spec-required → Plan excludes changing defaults, only adds warnings +- libxml2 is a customized fork → Plan includes audit step before update +- OpenSSL EOL not in scope → Explicitly documented as out-of-scope exclusion +- No performance baselines exist → Plan establishes timing baselines in Wave 1 +- ASAN will surface hundreds of existing bugs → Plan starts non-blocking, with suppression files +- Three zlib copies must be updated atomically → Plan consolidates in single task +- `const_cast` on `c_str()` in mkstemp() is UB → Fixed as part of SSL task +- WASM compatibility must be preserved → All platform-conditional code uses existing `#if defined()` patterns + +--- + +## Work Objectives + +### Core Objective +Harden the ONLYOFFICE Core conversion engine against known security vulnerabilities, improve conversion throughput through data structure and algorithm optimization, and establish a modern test infrastructure with sanitizer support and coverage reporting. + +### Concrete Deliverables +- `FileTransporter_curl.cpp` with SSL verification enabled + configurable CA bundle +- URL whitelist/blacklist system in FileTransporter for SSRF protection +- `MemoryLimit/ParentProcess/main.cpp` with input validation +- `vboxtester/main.cpp` with execve() replacing popen() +- `ooxml_crypt/main.cpp` with stdin password reading option +- `OOXML/Base/Unit.cpp` with cryptographic random for GUIDs +- `FontManager.cpp/h` with bounded default cache size (32 fonts) +- ~20 hot-path files with std::unordered_map replacing std::map +- `svg_parser.cpp` with optimized string building +- `CMakeLists.txt` + `common.cmake` with `-DENABLE_SANITIZERS` option +- GoogleTest integrated via `Common/3dParty/googletest/` +- Updated vendored: zlib 1.3.2, OpenJPEG 2.5.4, libxml2 2.12.x +- ~10 large project files split into logical modules +- Coverage reporting via lcov/gcovr in CI + +### Definition of Done +- [ ] `cmake --build build && ./Test/Applications/x2tTester/conversionTest.sh` passes +- [ ] `cmake -DENABLE_SANITIZERS=ON -B build-san && cmake --build build-san` succeeds +- [ ] `curl -v https://example.com` from x2t succeeds with SSL verification +- [ ] No new compiler warnings from vendored lib updates +- [ ] All file splits produce identical `.o` symbol tables + +### Must Have +- SSL verification enabled on Linux with graceful fallback +- SSRF URL whitelist configurable at runtime +- ASAN/UBSAN build option working in both CI and local dev +- All three zlib copies updated atomically +- OpenJPEG built with `OPJ_USE_SYSTEM_LIBS=ON` +- libxml2 customization audit documented before update +- Existing conversion test passes after every change +- Font cache has bounded default size +- SHA1/MD5 kept as defaults for OOXML/ODF compatibility + +### Must NOT Have (Guardrails) +- MUST NOT change OOXML/ODF encryption default algorithms (SHA1/MD5 are spec-required) +- MUST NOT break V8 build (requires clang-13 via GN) +- MUST NOT break WASM/Emscripten build path +- MUST NOT modify vendored LeptonLib or OpenJPEG source code +- MUST NOT change public API of conversion engine (x2t binary interface) +- MUST NOT introduce new external dependencies +- MUST NOT update OpenSSL, libtiff, or JasPer (explicitly out of scope) +- MUST NOT batch all 1,148 std::map replacements — target ~20 hot-path files only +- MUST NOT convert all 600+ new[] to RAII — target crypto and binary parsing only +- MUST NOT introduce async I/O (out of scope) +- MUST NOT change conversion test snapshot baselines +- MUST NOT remove `-O2` from default flags + +--- + +## Verification Strategy + +> **ZERO HUMAN INTERVENTION** — ALL verification is agent-executed. No exceptions. + +### Test Decision +- **Infrastructure exists**: PARTIAL — gtest placeholder exists but empty, no CI test framework +- **Automated tests**: Tests-after (establish infra first, then add tests) +- **Framework**: GoogleTest (via `Common/3dParty/googletest/`) +- **If TDD**: N/A — infrastructure must be built first + +### QA Policy +Every task MUST include agent-executed QA scenarios. +Evidence saved to `.sisyphus/evidence/task-{N}-{scenario-slug}.{ext}`. + +- **C++ Build/Compile**: Use Bash (cmake --build) — Build, check for warnings/errors, run tests +- **Library Updates**: Use Bash (cmake --build + ctest + conversionTest.sh) — Verify build and conversion +- **Security Fixes**: Use Bash (curl, strace) — Verify SSL handshake, test URL blocking, test input sanitization +- **Performance**: Use Bash (time, /usr/bin/time -v) — Measure conversion time and memory before/after +- **File Splits**: Use Bash (nm, diff) — Compare symbol tables before/after + +---
