CVE-2023-0215  (opens in a new tab)
CWE-416  (opens in a new tab)

How to fix?

Upgrade openssl-src to version 111.25.0, 300.0.12 or higher.

Overview

openssl-src is a crate that contains the logic to build OpenSSL and is intended to be consumed by the openssl-sys crate.

Affected versions of this package are vulnerable to Use After Free in the BIO_new_NDEF() function. A new filter BIO can be freed, with the function returning a NULL result indicating a failure. But the BIO passed by the caller still holds pointers to the previously freed filter BIO. This could allow an attacker to cause a crash.
