Description

snappy-java through 1.1.10.8 contains an out-of-bounds write vulnerability in Snappy.uncompress(ByteBuffer, ByteBuffer) because destination buffer capacity is never validated against decompressed size. Attackers can supply valid compressed data that decompresses larger than the destination buffer, causing writes past buffer boundaries and JVM termination.
