SSL: OpenSSL Invalid Session Ticket Denial of Service
A denial-of-service vulnerability exists in OpenSSL. It is due to a memory leak when OpenSSL processes invalid session tickets to verify their integrity. A remote, unauthenticated attacker can send crafted handshake messages to cause memory leaks, exhaust system memory and create a denial of service condition on an application using the vulnerable library.
Extended Description
Memory leak in the tls_decrypt_ticket function in t1_lib.c in OpenSSL before 0.9.8zc, 1.0.0 before 1.0.0o, and 1.0.1 before 1.0.1j allows remote attackers to cause a denial of service (memory consumption) via a crafted session ticket that triggers an integrity-check failure.
