Memory corruption in array-tools
An issue was discovered in the array-tools crate before 0.3.2 for Rust. Affected versions of this crate don't guard against panics, so that partially uninitialized buffer is dropped when user-provided T::clone() panics in FixedCapacityDequeLike<T, A>::clone(). This causes memory corruption.
