What is CVE-2019-12410?

The uninitialized memory exposure vulnerability in Apache Arrow arises when reading RLE null data from parquet files in versions 0.12.0 through 0.14.1. This flaw allows for uninitialized memory to remain accessible in various implementations, such as C++, Python, Ruby, and R. If this memory data is transmitted over the network, such as through the Flight protocol or stored in IPC streams and file formats, it poses significant risks regarding data leakage and unauthorized access. Users are advised to upgrade to Apache Arrow version 0.15.1 or later to mitigate these risks.
