Unfortunately a dangling pointer to the old location is left which results in an attempt to write to the previously freed location. This is likely to result in a crash, however it could potentially lead to execution of arbitrary code. This issue only affects OpenSSL 1.1.0a. This issue was reported to OpenSSL by Robert Święcki.
