* EMC Documentum eRoom Indexing Server
Authentication is not required to exploit this vulnerability.
The specific flaw exists within the bundled implementation of OpenText’s HummingBird Connector. When parsing a particular packet received from a TCP connection, the application will attempt to copy part of the packet’s contents into a buffer located on the stack. Due to not completely accommodating for the size of the data in the packet, the application will overwrite variables positioned after the buffer. This can lead to code execution under the context of the server.
EMC has issued an update to correct this vulnerability. More details can be found at:
