What to do

  1. See which version you have: cargo tree -i containers (it also shows which of your dependencies pulls it in).
  2. Update within your version requirement: cargo update -p containers. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for example containers = "0.9.11") or update the dependency that pulls it in.
  3. Check again with cargo audit, or paste your Cargo.lock into our Cargo.toml checker.

Details from the advisory

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.
