NVD Description

Note: Versions mentioned in the description apply only to the upstream libarrow package and not the libarrow package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

zstd-jni versions before 1.5.7-14 fail to validate offset and length parameters in the ZstdDictCompress constructor, allowing out-of-bounds memory reads. Attackers can supply untrusted offset or length values to read native heap memory into the compression dictionary, typically causing JVM crashes.
