-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of EMC RepliStor Server. User interaction is
not required to exploit this vulnerability.

The specific flaw exists in the RepliStor Server Service that listens
by default on TCP port 7144. The vulnerable function trusts a
user-supplied size value allowing an attacker to create an undersized
buffer. A later call to recv() overflows that buffer allowing for
arbitrary code execution in the context of the SYSTEM user.
