How to fix?

Upgrade OpenSSL to version 1.0.208 or higher.


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 Cryptographic Issues. OpenSSL is vulnerable to padding oracle attacks. The library does not check if there is enough data in both the MAC hash and padding bytes, allowing an attacker to recover the plain text by using the server as a padding oracle.

Note: This vulnerability exists because of an incorrect fix for CVE-2013-0169.
