RUSTSEC-2026-0078
Symbol confusion after hasher panic in `intaglio` interners
Affected versions of this crate can leave all SymbolTable variants in an
internally inconsistent state if a custom BuildHasher panics during
HashMap::insert and the caller recovers with catch_unwind.
The intern implementations committed a vec.push(...) before the matching
map.insert(...) completed. If hashing panicked in that window, later lookups
and inserts could observe diverging vec and map lengths.
In release builds, this can lead to symbol confusion where a newly interned string resolves to previously interned attacker-controlled contents. In debug builds, the same corruption is detected by follow-up assertions and results in panics.
The flaw was corrected in version 1.13.3 by making the vec mutation
transactional across unwind boundaries so partially inserted entries are rolled
back before the panic propagates.
