Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
