Description of the vulnerability 

The OpenSSL product uses a proprietary implementation of malloc to manage its memory.

However, when this feature is disabled with OPENSSL_NO_BUF_FREELIST, a memory area is not freed, and the ssl3_setup_read_buffer() function can, in multi-thread mode, reuse data from another SSL session.

An attacker can therefore establish a connection with a multi-threaded application linked to OpenSSL with OPENSSL_NO_BUF_FREELIST, in order to potentially inject data in the session of another user.
