9.8 (Critical) CVSS_V3 - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H CVSS Calculator

Summary

panic safety: double drop may happen within `util::{mutate, mutate2}`

Details

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.
