How to fix?

There is no fixed version for OpenSSL.

Overview

OpenSSL is a SSL/TLS and Crypto toolkit. Deprecated in Mac OS and gone in iOS, this spec gives your project non-deprecated OpenSSL support.

Affected versions of this package are vulnerable to Buffer Overflow. A miscalculation of a buffer size was found in openssl's SM2 decryption function, allowing up to 62 arbitrary bytes to be written outside of the buffer. A remote attacker could use this flaw to crash an application supporting SM2 signature or encryption algorithm, or, possibly, execute arbitrary code with the permissions of the user running that application.
