NVD Vulnerability Information
CVE-2015-0132
Summary

The XML parser in IBM Rational DOORS Next Generation 4.x before 4.0.7 iFix3 and 5.x before 5.0.2 and Rational Requirements Composer 2.x and 3.x before 3.0.1.6 iFix5 and 4.x before 4.0.7 iFix3 does not properly detect recursion during entity expansion, which allows remote attackers to cause a denial of service (memory consumption) via a crafted XML document containing a large number of nested entity references, a similar issue to CVE-2003-1564.
