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.

A flaw was found in zstd-jni. This vulnerability occurs due to insufficient validation of offset and length parameters within the `ZstdDictCompress` constructor. An attacker can exploit this by providing untrusted values, leading to an out-of-bounds memory read. This can result in the disclosure of sensitive native heap memory and cause the Java Virtual Machine (JVM) to crash, leading to a denial of service.

Red Hat is aware of an out-of-bounds read in zstd-jni caused by insufficient validation of offset and length values in the ZstdDictCompress constructor. An attacker who can influence these values may cause a JVM crash and potentially disclose native heap data. Affected Red Hat products are tracked through their existing remediation workflow. Update com.github.luben/zstd-jni to version 1.5.7-14 or later. Until updated, do not pass attacker-controlled offset or length values to ZstdDictCompress.
