What to do
- See which version you have:
cargo tree -i disrustor(it also shows which of your dependencies pulls it in). - Update within your version requirement:
cargo update -p disrustor. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for exampledisrustor = "0.3.0") or update the dependency that pulls it in. - Check again with
cargo audit, or paste your Cargo.lock into our Cargo.toml checker.
Details from the advisory
The RingBuffer type retrieves mutable references from the DataProvider in a non-atomic manner, potentially allowing the creation of multiple mutable references. RingBuffer also implements the Send and Sync traits for all types T.
This allows undefined behavior from the aliased mutable references as well as data races.
