Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The skiplist crate on crates.io, versions before 1.1.1, can reach freed memory when an element's Drop implementation panics during clear, retain, retain_mut or dedup_by. An attacker would need to supply a type whose Drop panics and then use the container afterward, which can lead to a use-after-free or double free. Upgrade to 1.1.1.
