zstd-jni is vulnerable to Out-of-bounds Read
82
High Risk
This Affects:
zstd-jniTL;DR
ZstdDictDecompress passes offset and length to the native dictionary constructor. The length check compares the array length with zero, which never fails, so an offset or length outside the array reaches the native constructor and can crash the JVM. The fix rejects an offset and length that fall outside the array.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and your code passes an offset or length into ZstdDictDecompress.
Background info
zstd-jni is vulnerable to Out-of-bounds Read in versions 1.2.0 - 1.5.7-13.
How to fix this
Upgrade the com.github.luben:zstd-jni library to the patch version.
