Title
Apache Arrow Rust: Improper validation of RunEndEncoded arrays allows out of bounds reads
Summary
Out-of-bounds read vulnerability in Apache Arrow Rust (`arrow` crate), from version 33.0.0 through to versions 57.3.1, 58.4.0, 59.3.1 and 60.0.0.
Improper validation of RunEndEncoded arrays in the ArrayData interface can allow reading data beyond the bounds of the child values array.
Users are recommended to upgrade to versions 60.1.0, 59.3.2, 58.4.1, 57.3.2 which fixes the issue.
