Description

zstd-jni versions 1.2.0 through 1.5.7-13 contain an out-of-bounds read vulnerability in the ZstdDictDecompress constructor because offset and length arguments are never validated against the dictionary array bounds. Attackers can supply arbitrary offset or length values to read memory past the end of the supplied array, potentially causing JVM termination.
