Overview
Affected versions of this package are vulnerable to Double Free via SnappyFramedInputStream in src/main/java/org/xerial/snappy/SnappyFramedInputStream.java. An attacker can make two SnappyFramedInputStream instances share the same backing array by supplying framed data with a large declared chunk length that triggers an allocation failure during buffer growth. When the stream returns its current direct and array buffers to the pool and the replacement allocation fails, close() can release the same buffers again. In deployments using the default caching buffer pool, a later stream may receive that reused buffer and read or overwrite another stream’s decompressed data.
Workarounds
- Discard the buffer pool after an
OutOfMemoryErrorduring decompression, so the same released buffers are not reused by laterSnappyFramedInputStreaminstances. - Pass a non-caching
BufferPooltoSnappyFramedInputStream, so buffers are not retained and handed out again to another stream after a failed allocation.
