snappy-java: JVM crash from unchecked ranges in Snappy.arrayCopy and SnappyOutputStream.rawWrite
The advisory, in context
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.
Affected packages
Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
