CVE-2023-34454

Summary

CVE-2023-34454 is a vulnerability affecting the snappy-java library, which is used for fast compression and decompression in Java. In versions prior to 1.1.10.1, an integer overflow can occur due to unchecked multiplications in the `compress` function. When the length of input data is not tested before being multiplied by two, the resulting integer can become negative. The rawCompress function, which uses this length value to allocate a byte array, does not check for negative values, leading to either a NegativeArraySizeException or an Access Violation error, depending on the size of the allocated buffer. This issue applies to various data types, including double, float, int, long, and short, each with different multipliers. The patch in version 1.1.10.1 mitigates this vulnerability.
