Descriptions

Off-by-one error in the XML signature feature in Apache XML Security for C++ 1.6.0, as used in Shibboleth before 2.4.3 and possibly other products, allows remote attackers to cause a denial of service (crash) via a signature using a large RSA key, which triggers a buffer overflow.

Error de superación de límite (off-by-one) en la característica de firma XML en Apache XML Security para C++ v1.6.0,usado en Shibboleth anterior a v2.4.3 y posiblemente otros productos, permite a atacantes remotos provocar una denegación de servicio (caída) a través de una firma utilizando una clave RSA larga, que provoca un desbordamiento de búfer.
