CVE-2021-25907: Double free in containers

August 25, 2021 (updated June 13, 2023)

Upon panic in a user-provided function f, fn mutate() & fn mutate2 drops twice a same object.

Affected versions of this crate did not guard against double drop while temporarily duplicating an object’s ownership with ptr::read().

Dropping a same object can result in memory corruption.

The flaw was corrected in version “0.9.11” by fixing the code to abort upon panic.
