HTTP: Apache OpenOffice dBase File Handling Buffer Overflow
This signature detects attempts to exploit a known vulnerability in the Apache OpenOffice. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.
Extended Description
Apache OpenOffice opens dBase/DBF documents and shows the contents as spreadsheets. DBF are database files with data organized in fields. When reading DBF data the size of certain fields is not checked: the data is just copied into local variables. A carefully crafted document could overflow the allocated space, leading to the execution of arbitrary code by altering the contents of the program stack. This issue affects Apache OpenOffice up to and including version 4.1.10
