2020-01-13tests/fuzzers: link fuzz binaries using $LIB_FUZZING_ENGINE. (#1230)Max Moroz
This was changed some time ago (https://google.github.io/oss-fuzz/getting-started/new-project-guide/) but the build didn't fail as there is a fallback mechanism. The main advantage of the new approach is that for libFuzzer this produces more performant binaries (as `$LIB_FUZZING_ENGINE` expands into `-fsanitize=fuzzer`, which links libFuzzer from the compiler-rt, allowing better optimization tricks). I'm also experimenting with dataflow (https://github.com/google/oss-fuzz/issues/1632) on your project, and the dataflow config doesn't have a fallback (as it's a new configuration), therefore I'm proposing a change to migrate from `-lFuzzingEngine` to `$LIB_FUZZING_ENGINE`.

There is currently a false positive ABI check failure between v2.3.1 and current. It disappears when removing the generated reports of v2.3.1 and recreating them. It is likely that some tooling has evolved since the initial v2.3.1 report generation.

2019-09-04openjp2/j2k: Validate all SGcod/SPcod/SPcoc parameter values.Sebastian Rasmussen
Previously the multiple component transformation SGcod(C) and wavelet transformation SPcod(H)/SPcoc(E) parameter values were never checked, allowing for out of range values. The lack of validation allowed the bit stream provided in issue #1158 through. After this commit an error message points to the marker segments' parameters as being out of range. input/nonregression/edf_c2_20.jp2 contains an SPcod(H) value of 17, but according to Table A-20 of the specification only values 0 and 1 are valid. input/nonregression/issue826.jp2 contains a SGcod(B) value of 2, but according to Table A-17 of the specification only values 0 and 1 are valid. input/nonregression/oss-fuzz2785.jp2 contains a SGcod(B) value of 32, but it is likewise limited to 0 or 1. These test cases have been updated to consistently fail to parse the headers since they contain out of bounds values. This fixes issue #1210.
2019-09-04openjp2/j2k: Make comments adhere to specification.Sebastian Rasmussen
The function is used to read both SPcod and SPcoc, so all comments should refer to both marker segments' parameter names.
