Upgrade SLES:16.0.0 zstd-jni to version 1.5.7.16-160000.1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream zstd-jni package and not the zstd-jni package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

zstd-jni before 1.5.7-14 fails to validate the samples buffer capacity in Zstd.trainFromBufferDirect, allowing attackers to read past buffer boundaries by supplying oversized per-sample lengths. Attackers can trigger out-of-bounds memory access by providing crafted sample length arrays that cause the native implementation to walk past the buffer allocation, resulting in JVM termination.
