SCA: security update for org.xerial.snappy:snappy-java (GHSA-fjpj-2g6w-x25r)

high Tenable Self-Hosted Container Security Plugin ID 414563

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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 an unrecoverable fatal error. The function
`compress(char[] input)` in the file `Snappy.java` receives an array of characters and compresses it. It
does so by multiplying the length by 2 and passing it to the rawCompress` function. Since the length is
not tested, the multiplication by two can cause an integer overflow and become negative. The rawCompress
function then uses the received length and passes it to the natively compiled maxCompressedLength
function, using the returned value to allocate a byte array. Since the maxCompressedLength function treats
the length as an unsigned integer, it doesn’t care that it is negative, and it returns a valid value,
which is casted to a signed integer by the Java engine. If the result is negative, a
`java.lang.NegativeArraySizeException` exception will be raised while trying to allocate the array `buf`.
On the other side, if the result is positive, the `buf` array will successfully be allocated, but its size
might be too small to use for the compression, causing a fatal Access Violation error. The same issue
exists also when using the `compress` functions that receive double, float, int, long and short, each
using a different multiplier that may cause the same issue. The issue most likely won’t occur when using a
byte array, since creating a byte array of size 0x80000000 (or any other negative value) is impossible in
the first place. Version 1.1.10.1 contains a patch for this issue. (CVE-2023-34454)
