Linux Distros Unpatched Vulnerability : CVE-2025-66566
high Nessus Plugin ID 277643
Language:
Synopsis
The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.Description
The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.- yawkat LZ4 Java provides LZ4 compression for Java. Insufficient clearing of the output buffer in Java- based decompressor implementations in lz4-java 1.10.0 and earlier allows remote attackers to read previous buffer contents via crafted compressed input. In applications where the output buffer is reused without being cleared, this may lead to disclosure of sensitive data. JNI-based implementations are not affected.
This vulnerability is fixed in 1.10.1. (CVE-2025-66566)
Note that Nessus relies on the presence of the package as reported by the vendor.
