| Titel | luben zstd-jni 1.5.7-13 Missing Bounds Check |
|---|
| Beschreibung | Right after confirming the broken bounds check in ZstdDictCompress's constructor, I checked the decompression-side sibling ZstdDictDecompress(byte[] dict, int offset, int length) — it has the same shape of bug but is worse: there's no validation at all, not even the partial check its compression counterpart has. I confirmed this with a real crash. No check on offset, length, or their relationship to dict.length whatsoever. The native function forwards them straight into ZSTD_createDDict. |
