CVE-2024-27284Network attack vector

Application crash via stale iterator item access

Published Feb 28, 2024 · Updated Aug 12, 2024

Use after free in cassandra-rs before 3.0.0 allows remote attackers to crash a consuming application through iterator-driven query results. The Rust bindings expose driver iterators as ordinary iterators even though calling next() invalidates the previously returned row or value, leaving retained items backed by freed memory. Reachability requires consuming code to retain an item across another next() call; affected code usually fails immediately, while code that processes each item before advancing is unaffected.
