It was found that the GnuTLS implementation of HMAC-SHA-256 was vulnerable to a Lucky thirteen style attack. Remote attackers could use this flaw to conduct distinguishing attacks and plaintext-recovery attacks via statistical analysis of timing data using crafted packets. Se ha detectado que la implementación GnuTLS de HMAC-SHA-256 era vulnerable a un ataque de estilo Lucky Thirteen. Los atacantes remotos podrían utilizar este fallo para realizar ataques de distinción y de recuperación en texto plano mediante análisis estadísticos de datos temporales mediante paquetes manipulados.
