-- CVE ID:
CVE-2011-2220

-- CVSS:
9.7, (AV:N/AC:L/Au:N/C:C/I:C/A:P)

-- Affected Vendors:
Novell

-- Affected Products:
Novell File Reporter

vulnerability by Digital Vaccine protection filter ID 11279.

-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell File Reporter Engine. Authentication
is not required to exploit this vulnerability.

The specific flaw exists within NFREngine.exe which communicates with
the Agent component over HTTPS on TCP port 3035. When parsing tags
inside the <RECORD> element, the application lacks a size check before
pushing strings to a memcpy. An attacker can leverage this to corrupt
the thread's stack. This vulnerability can result in remote code
execution under the context of the SYSTEM account.

-- Vendor Response:
Novell has issued an update to correct this vulnerability. More
details can be found at:
