Vulnerability Title
zstd-jni 1.2.0 through 1.5.7-13 Out-of-Bounds Read via ZstdDictDecompress
Source: CVE Program / CVE List V5
Vulnerability 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.
