Hi Here are the unit tests for PoDoFo::PdfParser I’ve been working on. I’ve just included the .cpp and .h files rather than a patch since they’re new files.
I’ve not included a patch for CMakeLists.txt – but I think all that’s needed is adding ParserTests.cpp to the CMakeLists.txt file for the unit tests (CppUnit takes care of everything else) What’s tested: * CVE-2017-8053, CVE-2015-8981, CVE-2017-5853, CVE-2018-5296 CVE-2017-8787, CVE-2018-5295 CVE-2017-8378 * Stress testing of ReadXRefSubsection( nFirstObject, nNumObjects ) with lots of different values for nFirstObject and nNumObjects * Stress testing of ReadXRefSubsection with different values supplied to PdfParser::SetMaxObjectCount * Testing other PdfParser functions for infinite recursion, out-of-memory handling etc * See comments in ParserTests.h * 2k lines of code but still lots more that can be tested… Test results * Stack overflow in ReadXRefContents and ReadXRefStreamContents see https://sourceforge.net/p/podofo/tickets/7/ * If this is patched (I have a patch) then the tests run successfully on Windows 10 with VC++ 2015 and macOS 10.11 with XCode 8/Clang and AddressSanitizer enabled * There’s a problem on macOS 10.13 (a SIGKILL when allocating a lot of memory) but it’s probably a macOS problem (10.13 is very buggy) Not tested: * Win64 build * Linux with GCC - might need a small change to get low memory tests to work – see comment in canOutOfMemoryKillUnitTests() at end of ParserTests.cpp Best Regards Mark -- Mark Rogers - mark.rog...@powermapper.com<mailto:mark.rog...@powermapper.com> PowerMapper Software Ltd - www.powermapper.com Registered in Scotland No 362274 Quartermile 2 Edinburgh EH3 9GL
