RUSTSEC-2021-0114 (CVE-2021-45705)

Vulnerability from osv_rustsec – Published: 2021-09-23 12:00 – Updated: 2023-06-13 13:10 – Source website

Summary

Aliased mutable references from `tls_rand` & `TlsWyRand`

Details

TlsWyRand's implementation of Deref unconditionally dereferences a raw pointer, and returns multiple mutable references to the same object, which is undefined behavior.
