GHSA-6CX8-RJF8-PR8G yawkat LZ4 Java: LZ4DecompressorWithLength allocates the unvalidated size from the 4-byte length header, so a 5-byte input triggers a 1 GiB allocation and OutOfMemoryError
Summary LZ4DecompressorWithLength.decompressbyte, int allocates whatever size the 4-byte length header declares, before it reads a single byte of compressed data. A 5-byte input whose header says 0x40000000 makes the JVM commit a gigabyte and can cause heap exhaustion. Details...
CVE-2026-106449
A flaw was found in lz4-java. This issue can lead to a Denial of Service DoS when the LZ4 input stream is configured not to stop upon encountering empty blocks. In this non-default configuration, consecutive empty blocks are processed via recursive calls rather than iterative handling. A remote...
CVE-2026-106453
A flaw was found in lz4-java. The library trusts the decompressed length header in compressed input before validating the input data, leading to uncontrolled memory allocation. A remote attacker can exploit this vulnerability by supplying a specially crafted input that specifies an excessively...
CVE-2026-106452
A flaw was found in lz4-java. A remote attacker can trigger a Denial of Service DoS by providing a crafted compressed data stream with an oversized block header. During decompression, the input stream allocates memory based on this attacker-controlled size field before reading the actual payload,...
CVE-2026-106451
A flaw was found in lz4-java. When extracting native libraries, the application writes temporary files to a shared directory using predictable file paths without exclusive file creation controls. A local attacker with access to the shared directory could exploit this race condition to replace the...
CVE-2026-106450
A flaw was found in lz4-java. By supplying a specially crafted stream containing many small frame headers, a remote attacker can trigger disproportionate memory allocations during decompression. This excessive allocation consumes substantial memory and processing resources, potentially leading to...
yawkat LZ4 Java: LZ4BlockInputStream allocates an unvalidated compressed length from the stream header
LZ4BlockInputStream grows its compressed-input buffer to the attacker-controlled compressedLen value from the legacy LZ4Block stream header before reading any payload bytes. A header-only input can therefore trigger a near-2 GiB allocation and exhaust the JVM heap...
yawkat LZ4 Java: LZ4FrameInputStream reallocates block buffers for every frame, allowing CPU and GC amplification from small inputs
LZ4FrameInputStream allocates two new buffers of the frame's maximum block size, up to 4 MiB each, every time it reads a frame header. Because concatenated frames are read by default, an input made of many minimal empty frames forces about 8 MiB of zeroed heap allocation for every 11 input bytes...
