description

Apache Arrow Rust's arrow crate improperly validates RunEndEncoded arrays supplied through the ArrayData interface. An attacker able to provide such array data may cause reads beyond the associated child values array.

mitigation

Update the arrow crate to version 60.1.0 or later. Ensure applications do not accept untrusted array data until the dependency is updated.

fixed in 60.1.0
