http://www.zerodayinitiative.com/advisories/ZDI-07-078.html
December 17, 2007

-- CVE ID:
CVE-2007-6281

-- Affected Vendor:

-- Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of St. Bernard Open File Manager.
Authentication is not required to exploit this vulnerability.

The specific flaw resides in the Open File Manager service, ofmnt.exe,
which listens by default on a random TCP port near 1000. The process
blindly copies user-suppled data to a static heap buffer. By supplying
an overly large amount of data, an attacker can overflow that buffer
leading to arbitrary code execution in the context of the SYSTEM user.


-- Vendor Response:
St. Bernard has issued an update to correct this vulnerability. Version
9.6 build 602 available to customers addresses this issue. Other
affected vendors such as Hewlett-Packard have made fixes available to
customers as well.

-- Disclosure Timeline:
2007.07.20 - Vulnerability reported to vendor
2007.12.17 - Coordinated public release of advisory

-- Credit:
This vulnerability was discovered by an anonymous researcher.
