CVE-2015-0132
HighSummary
The XML parser in IBM Rational DOORS Next Generation and Rational Requirements Composer improperly detects recursion during entity expansion, which can lead to denial of service through memory consumption. Attackers can exploit a crafted XML document containing a large number of nested entity references.
Risk Assessment
The organization may experience downtime due to excessive memory consumption, affecting service availability. Potential attacks could lead to significant disruptions in application operation.
Recommendation
It is recommended to upgrade to IBM Rational DOORS Next Generation version 4.0.7 iFix3 or 5.0.2 and Rational Requirements Composer version 3.0.1.6 iFix5 to mitigate the risk associated with this vulnerability.

Original NVD description (English source)
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.
