-- 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.

-- Vendor Response:

EMC has issued updates to correct this vulnerability. More details can

be found in knowledge base article emc168869 available from

powerlink.emc.com. EMC customers can further contact EMC Software
