Unless I'm mistaken, the following memcmp is vulnerable to a remote timing attack. https://github.com/openssl/openssl/blob/master/ssl/ssl_lib.c#L1974 static int ssl_session_cmp(const SSL_SESSION *a,const SSL_SESSION *b) { if (a->ssl_version != b->ssl_version) return(1); if (a->session_id_length != b->session_id_length) return(1); return(memcmp(a->session_id,b->session_id,a->session_id_length)); } On Tue, 2014-04-08 at 03:10 +0300, Kirils Solovjovs wrote:
