Unspecified vulnerability in the Oracle HTTP Server component in Oracle Fusion Middleware 11.1.1.7.0, 12.1.2.0, and 12.1.3.0 allows remote attackers to affect availability via unknown vectors related to Web Listener, a different vulnerability than CVE-2013-0338, CVE-2013-2877, and CVE-2014-0191.

The xmlParserHandlePEReference function in parser.c in libxml2 before 2.9.2, as used in Web Listener in Oracle HTTP Server in Oracle Fusion Middleware 11.1.1.7.0, 12.1.2.0, and 12.1.3.0 and other products, loads external parameter entities regardless of whether entity substitution or validation is enabled, which allows remote attackers to cause a denial of service (resource consumption) via a crafted XML document.
