GHSA-XX22-P4CH-683R LZ4 Java: Native XXHash implementations can crash the JVM when passed invalid byte array ranges
Summary Insufficient validation of byte array arguments in JNI-based XXHash implementations in lz4-java 1.11.0 and earlier allows callers to crash the JVM by passing an invalid array reference or invalid range to native XXHash methods. This affects applications where an attacker can influence the...
NULL Pointer Dereference
Overview org.lz4:lz4-java is a Java port of the LZ4 compression algorithm and the xxHash hashing algorithm. Affected versions of this package are vulnerable to NULL Pointer Dereference and out-of-bounds read in the native XXHash implementations reached through XXHashFactory.nativeInstance, where...

netty: io.netty/netty-codec-compression: io.netty/netty-codec: Netty: Denial of Service via excessive memory allocation in LZ4FrameDecoder
A flaw was found in Netty, an asynchronous, event-driven network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted LZ4 compressed data stream. This can cause the Lz4FrameDecoder to allocate a large amount of memory up to 32 MB per block before...
