This package is used to read TNEF files (Microsoft Outlook and Microsoft Exchange Server). If an application uses poi-scratchpad to parse TNEF files and the application allows untrusted users to supply them, then a carefully crafted file can cause an Out of Memory exception. This issue affects poi-scratchpad version 5.2.0 and prior versions. Users are recommended to upgrade to poi-scratchpad 5.2.1. This issue is being tracked as https://bz.apache.org/bugzilla/show_bug.cgi?id=65899 Credit: Apache POI would like to thank Craig Haft of Yahoo Inc. for reporting and providing a patch for this issue.
