opj_jp2_read_header: Check for error after parsing header.

2025-01-16T01:24:21Z

Consider the case where the caller has not set the p_image pointer to NULL before calling opj_read_header(). If opj_j2k_read_header_procedure() fails while obtaining the rest of the marker segment when calling opj_stream_read_data() because the data stream is too short, then opj_j2k_read_header() will never have the chance to initialize p_image, leaving it uninitialized. opj_jp2_read_header() will check the p_image value whether opj_j2k_read_header() suceeded or failed. This may be detected as an error in valgrind or ASAN. The fix is to check whether opj_j2k_read_header() suceeded before using the output argument p_image.

Fix Heap-buffer-overflow READ in opj_jp2_apply_pclr (#1441)

2022-08-12T13:48:41Z

The issue was found while fuzzing opencv: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=47342 The read overflow triggered by reading `src[j]` in ```cpp for (j = 0; j < max; ++j) { dst[j] = src[j]; } ``` The max is calculated as `new_comps[pcol].w * new_comps[pcol].h`, however the `src = old_comps[cmp].data;` which may have different `w` and `h` dimensions.
