Integer Overflow

snappy-java is vulnerable to Integer Overflow. The vulnerability exists because the compress function receives an array of characters and multiplies the value by two, and passes it to the rawCompress function of Snappy.java which does not properly check the length and causes an integer overflow, or the value becomes negative which leads to java.lang.NegativeArraySizeException exception if the size is too small to use for the compression, causing a fatal Access Violation error, allowing an attacker to crash the application.
