How to fix?

There is no fixed version for RHEL:7 snappy-java.

NVD Description

Note: Versions mentioned in the description apply only to the upstream snappy-java package and not the snappy-java package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

snappy-java is a fast compressor/decompressor for Java. Due to unchecked multiplications, an integer overflow may occur in versions prior to 1.1.10.1, causing a fatal error.

The function shuffle(int[] input) in the file BitShuffle.java receives an array of integers and applies a bit shuffle on it. It does so by multiplying the length by 4 and passing it to the natively compiled shuffle function. Since the length is not tested, the multiplication by four can cause an integer overflow and become a smaller value than the true size, or even zero or negative. In the case of a negative value, a java.lang.NegativeArraySizeException exception will raise, which can crash the program. In a case of a value that is zero or too small, the code that afterwards references the shuffled array will assume a bigger size of the array, which might cause exceptions such as java.lang.ArrayIndexOutOfBoundsException.

The same issue exists also when using the shuffle functions that receive a double, float, long and short, each using a different multiplier that may cause the same issue.

Version 1.1.10.1 contains a patch for this vulnerability.
