How to fix?

Upgrade OpenSSL to version 1.0.8 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 Out-of-Bounds. OpenSSL is vulnerable to denial of service (DoS) attacks through memory consumption and application crash. This is caused because the dtls1_clear_queues function in d1_lib.c frees data not taking into account that application data could arrive between the ChangeCipherSpec message and the Finished message. This can cause the DTLS peer to buffer the application data and cause a segmentation fault.
