yawkat LZ4 Java: Native library extraction to a shared temporary directory is vulnerable to file replacement by another local user

Summary When no system-installed liblz4-java is found, net.jpountz.util.Native.load extracts the bundled native library to java.io.tmpdir and loads it with System.load. The path of the extracted library can be predicted before it is created, and the library file is opened without exclusive...

Insecure Temporary File

Overview Affected versions of this package are vulnerable to Insecure Temporary File in the process that extracts and loads the native library via net.jpountz.util.Native.load. An attacker can execute arbitrary code by pre-creating a malicious file in a shared temporary directory, causing the...

Insecure Temporary File

Overview org.lz4:lz4-java is a Java port of the LZ4 compression algorithm and the xxHash hashing algorithm.

GHSA-343H-94H5-C4WR yawkat LZ4 Java: LZ4BlockInputStream with stopOnEmptyBlock=false recurses once per empty block, causing StackOverflowError

Summary When LZ4BlockInputStream is configured with stopOnEmptyBlock = false the mode for reading concatenated block streams, it handles each empty block by calling refill recursively. A long run of empty blocks exhausts the thread stack and throws StackOverflowError out of read or skip. Details ...
