CyberRota Analysis
AI-GeneratedThe yawkat LZ4 Java library, prior to version 1.11.4, is vulnerable to a StackOverflowError when processing a specially crafted compressed stream containing a sequence of empty LZ4 blocks. This vulnerability can lead to denial of service by exhausting the decoding thread's stack, although it does not result in memory corruption. Java developers using affected versions should prioritize upgrading to version 1.11.4 to mitigate this risk.

Original NVD Description
yawkat LZ4 Java provides LZ4 compression for Java. Prior to 1.11.4, net.jpountz.lz4.LZ4BlockInputStream configured with stopOnEmptyBlock set to false handles each well-formed empty LZ4Block by recursively calling refill(), allowing a long sequence of empty blocks in an attacker-controlled compressed stream to exhaust the decoding thread's stack and throw StackOverflowError. The default stopOnEmptyBlock setting is true and is not affected, and the issue does not cause memory corruption. This issue is fixed in version 1.11.4.
