Description

Arrow2 allows double free in safe code

The struct Ffi_ArrowArray implements #derive(Clone) that is inconsistent with

its custom implementation of Drop, resulting in a double free when cloned.

Cloning this struct in safe results in a segmentation fault, which is unsound.

This derive was removed from this struct. All users are advised to either:

  • bump the patch version of this crate (for versions v0.7,v0.8,v0.9), or
  • migrate to a more recent version of the crate (when using <0.7).

Doing so elimitates this vulnerability (code no longer compiles).

Weakness class

GHSA-5j8w-r7g8-5472 is classified as CWE-415: Double Free. The same allocation is released twice, corrupting allocator bookkeeping.
