CVE-2015-0226

Apache WSS4J versiones anteriores a 1.6.17 y versiones 2.0.x anteriores a 2.0.2, filtra información inapropiadamente sobre fallos de descifrado cuando se descifra una clave o datos de mensajes cifrados, lo que facilita a atacantes remotos recuperar el formulario de texto plano de una clave simétrica por medio de una serie de mensajes diseñados. NOTA: esta vulnerabilidad se presenta debido a una corrección incompleta de CVE-2011-2487.

It was found that a prior countermeasure in Apache WSS4J for Bleichenbacher's attack on XML Encryption (CVE-2011-2487) threw an exception that permitted an attacker to determine the failure of the attempted attack, thereby leaving WSS4J vulnerable to the attack. The original flaw allowed a remote attacker to recover the entire plain text form of a symmetric key.

Red Hat JBoss Fuse, based on Apache ServiceMix, provides a small-footprint, flexible, open source enterprise service bus and integration platform. The following security fixes are addressed in this release: It was found that async-http-client would disable SSL/TLS certificate verification under certain conditions, for example if HTTPS communication also used client certificates. A man-in-the-middle attacker could use this flaw to spoof a valid certificate. It was found that async-http-client did not verify that the server hostname matched the domain name in the subject's Common Name or subjectAltName field in X.509 certificates. This could allow a man-in-the-middle attacker to spoof an SSL server if they had a certificate that was valid for any domain name.
