+ <p>If mbedtls_ssl_set_session() or mbedtls_ssl_get_session() were to
+ fail with MBEDTLS_ERR_SSL_ALLOC_FAILED (in an out of memory
+ condition), then calling mbedtls_ssl_session_free() and
+ mbedtls_ssl_free() in the usual manner would cause an internal
+ session buffer to be freed twice, due to two structures both having
+ valid pointers to it after a call to ssl_session_copy().</p>
+ <p>An attacker could potentially trigger the out of memory condition,
+ and therefore use this bug to create memory corruption, which could
+ then be further exploited or targetted.</p>
