Summary
snappy-java: JVM crash from unchecked ranges in Snappy.arrayCopy and SnappyOutputStream.rawWrite
Details

Impact

Snappy.arrayCopy(Object src, int offset, int byteLength, Object dest, int destOffset) called a native memcpy without validating the ranges. A negative or oversized byteLength or offset read or wrote outside the arrays and crashed the JVM. SnappyOutputStream.rawWrite and SnappyInputStream.rawRead, and therefore the typed-array write/read methods, pass caller-supplied ranges to this method.

Patches

Fixed in 1.1.10.9 (#741). Snappy.arrayCopy checks both ranges before copying. The stream read/write methods validate offsets and lengths, and reject typed-array ranges whose byte size overflows int.

Workarounds

Validate offsets and lengths before calling these methods.

Severity
5.9 (Medium)
