EMC RepliStor Multiple Heap Overflow Vulnerabilities
------------------------------------------------------------------------


SUMMARY

<http://software.emc.com/products/software_az/replistor.htm> EMC
RepliStor is "a data backup and recovery application for Windows". Remote
exploitation of multiple heap overflow vulnerabilities in EMC Corp.'s
RepliStor could allow an unauthenticated attacker to execute arbitrary
code with SYSTEM privileges.

DETAILS

Vulnerable Systems:
* EMC RepliStor version 6.2 SP2

Multiple vulnerabilities exist within the code responsible for
compression. In each case, data is decompressed without consideration for
the size of the destination buffer. This results in an exploitable heap
overflow.

Analysis:
Exploitation of these vulnerabilities results in the execution of
arbitrary code with the privileges of the RepliStor Server or Control
Server, usually SYSTEM. In order to exploit these vulnerabilities, an
attacker needs to be able to connect to the targeted server on TCP port
7144 or 7145. No authentication is required to reach the vulnerable code
paths.
