Vulnerability from github – Published: 2021-08-25 20:57 – Updated: 2021-08-24 18:04

Summary

Data races in generator

Details

The Generator type is an iterable which uses a generator function that yields values. In affected versions of the crate, the provided function yielding values had no Send bounds despite the Generator itself implementing Send.

The generator function lacking a Send bound means that types that are dangerous to send across threads such as Rc could be sent as part of a generator, potentially leading to data races.

This flaw was fixed in commit f7d120a3b by enforcing that the generator function be bound by Send.

Severity

5.9 (Medium)

RUSTSEC-2020-0151 (CVE-2020-36471)

Vulnerability from osv_rustsec – Published: 2020-11-16 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

Generators can cause data races if non-Send types are used in their generator functions

Details

The generator function lacking a Send bound means that types that are dangerous to send across threads such as Rc could be sent as part of a generator, potentially leading to data races.

This flaw was fixed in commit f7d120a3b by enforcing that the generator function be bound by Send.
