Multiple Vendor Calendar Manager RPC Service Remote Code Execution Vulnerability

Dear Friends,
This is a vulnerability related to remote code execution and by using it any attacker can attack on your system.
So be prepared to face it...

Vulnerability Details:
This vulnerability allows attackers to execute arbitrary code on
vulnerable installations of the Calendar Manager RPC Service.
Authentication is not required to exploit this vulnerability.

The specific flaw exists within the CMSD server (rpc.cmsd) which listens
by default on UDP port 32768. The process does not properly handle large
XDR-encoded ASCII strings to RPC call 10 followed by RPC call 6. This
can be abused by an attacker to overflow a buffer on the remote host.
Successful exploitation can result in arbitrary code execution.

iDefense Security Advisory 02.08.11: Microsoft Windows Picture and Fax Viewer Library

Dear All,

There is a vulnerability found in Microsoft's Windows Picture and Fax Viewer.
The description is mentioned below, so please remember it whenever you people are using it.

Vulnerability Description

I. BACKGROUND

The Windows Picture and Fax Viewer "shimgvw.dll" library is used by
Windows Explorer to generate thumbnail previews for media files.

II. DESCRIPTION

Remote exploitation of a buffer overflow vulnerability in multiple
versions of Microsoft Corp.'s Windows could allow attackers to execute
arbitrary code on the targeted host. <BR><BR> An integer overflow
vulnerability exists in the "shimgvw" library. During the processing of
an image within a certain function, a bitmap containing a large
"biWidth" value can be used to cause an integer calculation overflow.
This condition can lead to the overflow of a heap buffer and may result
in the execute arbitrary code on the targeted host.

III. ANALYSIS

Exploitation could allow attackers to execute arbitrary code on the
targeted host under the privileges of the current logged-on user.
Successful exploitation would require the attacker to entice his or her
victim into viewing a specially-crafted thumbnail leveraging the
vulnerability. <BR><BR> Some vectors of attack include e-mail, the
browser and network shares. In an e-mail-based attack, the attacker
must entice his or her victim into opening or previewing a
specially-crafted Office document containing a specially-crafted
thumbnail. In a browser-based attack, the victim must simply view a
maliciously crafted website. In a network share attack, such as UNC or
WebDAV, an attacker would require the victim to simply navigate to the
folder containing the crafted thumbnail.

IV. DETECTION

iDefense has confirmed the existence of this vulnerability in Microsoft
Windows XP SP3. A full list of vulnerable Microsoft products can be
found in Microsoft Security Bulletin MS11-006.
