CyberRota Analysis

AI-Generated

The vulnerability affects zstd-jni versions 1.4.8-4 through 1.5.7-13, where improper validation of negative length parameters in the ZstdInputStreamNoFinalizer.read() method can lead to infinite loops. This allows attackers to exploit the issue, causing the read method to block all other threads from accessing the stream, potentially leading to denial of service. Organizations utilizing these versions should prioritize remediation to mitigate the risk of service disruption.

Original NVD Description

zstd-jni versions 1.4.8-4 through 1.5.7-13 fail to validate negative length parameters in ZstdInputStreamNoFinalizer.read(), allowing attackers to trigger infinite loops. Attackers can pass negative length values to cause the read method to spin indefinitely while holding the stream monitor, blocking all other threads from accessing the stream.
