## Description

snappy-java through 1.1.10.8 contains a buffer overflow vulnerability in
typed Snappy.uncompress\*Array methods that allocate output arrays by
dividing uncompressed length by element size but pass the undivided length
to native code. Attackers controlling compressed input can cause misaligned
length values to write past array bounds with attacker-controlled bytes,
corrupting heap memory.
