iq80 Snappy is a compression/decompression library. When uncompressing certain data, Snappy tries to read outside the bounds of the given byte arrays. Because Snappy uses the JDK class `sun.misc.Unsafe` to speed up memory access, no additional bounds checks are performed and this has similar security consequences as out-of-bounds access in C or C++, namely it can lead to non-deterministic behavior or crash the JVM. iq80 Snappy is not actively maintained anymore. As quick fix users can upgrade to version 0.5.

### Summary iq80 Snappy performs out-of-bounds read access when uncompressing certain data, which can lead to a JVM crash. ### Details When uncompressing certain data, Snappy tries to read outside the bounds of the given byte arrays. Because Snappy uses the JDK class `sun.misc.Unsafe` to speed up memory access, no additional bounds checks are performed and this has similar security consequences as out-of-bounds access in C or C++, namely it can lead to non-deterministic behavior or crash the JVM. iq80 Snappy is not actively maintained anymore. As quick fix users can upgrade to version 0.5, but in the long term users should prefer migrating to the Snappy implementation in https://github.com/airlift/aircompressor (version 0.27 or newer). ### Impact When uncompressing data from untrusted users, this can be exploited for a denial-of-service attack by crashing the JVM.
