CVE-2020-36215

An issue was discovered in the hashconsing crate before 1.1.0 for Rust. Because HConsed does not have bounds on its Send trait or Sync trait, memory corruption can occur.

An issue was discovered in the hashconsing crate before 1.1.0 for Rust. Because HConsed does not have bounds on its Send trait or Sync trait, memory corruption can occur.

Affected versions of `hashconsing` implements `Send`/`Sync` for its `HConsed` type without restricting it to `Send`able types and `Sync`able types. This allows non-`Sync` types such as `Cell` to be shared across threads leading to undefined behavior and memory corruption in concurrent programs.

Se detectó un problema en la crate hashconsing versiones anteriores a 1.1.0 para Rust. Debido a que HConsed no posee límites en su atributo Send o Sync, una corrupción de la memoria puede ocurrir
