Apache POI contains a flaw that may allow a remote denial of service. The issue is triggered when a validation check of the length attribute is not performed in the UnhandledDataStructure() constructor in src/org/apache/poi/hwpf/model/UnhandledDataStructure.java when handling CDF or CFBF files. This will result in a loss of availability for the program.
