Internet Bug Bounty: OCSP Status Request extension unbounded memory growth (CVE-2016-6304)

A malicious client can send an excessively large OCSP Status Request extension. If that client continually requests renegotiation, sending a large OCSP Status Request extension each time, then there will be unbounded memory growth on the server. This will eventually lead to a Denial Of Service...

Denial Of Service (DoS)

OpenSSL is vulnerable to Denial Of Service DoS. A malicious user can send multiple large OCSP Status Request extension to the server. causing it to run out of memory and crash...
