This uses a seh overwrite method, which takes advantage of the SEH being placed
in multiple locations over the different OS's. Because of this, it should be
completely universal. :).
Also, we added SEH for enterprise and Standard, if you have a diff 2k3 then deal with it and write your own in.

iDEFENSE Security Advisory 03.01.05 - Remote exploitation of a stack-based buffer overflow vulnerability in the The Synchronized Multimedia Integration Language (smil) file format parser within various versions of RealNetworks Inc.'s RealPlayer could allow attackers to execute arbitrary code.

RealNetworks RealPlayer .smil Buffer Overflow Vulnerability

iDEFENSE Security Advisory 03.01.05
www.idefense.com/application/poi/display?id=209&type=vulnerabilities
March 1, 2005

I. BACKGROUND

RealPlayer is an application for playing various media formats,
developed by RealNetworks Inc. For more information, visit
http://www.real.com/.

II. DESCRIPTION

Remote exploitation of a stack-based buffer overflow vulnerability in
the The Synchronized Multimedia Integration Language (smil) file format
parser within various versions of RealNetworks Inc.'s RealPlayer could
allow attackers to execute arbitrary code.

The vulnerability specifically exists due to an unbounded string copying
operation. The vulnerable code is shown below:

datatype/smil/renderer/smil1/smlparse.cpp
CSmil1Parser::testAttributeFailed(SMIL1Node* pNode)
line 2878
***
     if(HXR_OK == rc)
        {
            UINT32 ulScreenHeight = 0;
            UINT32 ulScreenWidth = 0;

            const char* pScreenSize = (const char*)pBuf->GetBuffer();
            // format is screen-height "X" screen-width
            char tmp[256]; /* Flawfinder: ignore */
            strcpy(tmp, pScreenSize); /* Flawfinder: ignore */
***


The pBuf object's datapointer (which is what GetBuffer uses internally)
is pointing at the screen-size attribute in the user-supplied smil file.
This allows a fixed stack buffer to be overwritten with user-supplied
data. An attacker could use this stack overwrite to manipulate a saved
return address or Structured Exception Handler, allowing for arbitrary
code execution.

In order to trigger this vulnerability, one would need an otherwise
valid .smil file with the following line added in an appropriate
section: <text src="1024_768.en.txt" region="size" system-screen-
size="LONGSTRINGX768">

Note that "LONGSTRING" should be more than 256 bytes in order to cause
stack corruption.

III. ANALYSIS

Exploitation allows for arbitrary code execution as the user who opened
the .smil file.

Exploitation requires an attacker to craft a malicious .smil and
convince a user to open it. An attacker could also force a web browser
to refresh and automatically load the .smil file from a normal web page
under the attacker's control. In default installations of RealPlayer
under Windows, Internet Explorer will not prompt the user for an action
when encountering a .smil file. It will open it without delay, thus
allowing a more effective method of exploitation.

IV. DETECTION

iDEFENSE Labs has confirmed that Real Networks Inc.'s RealPlayer 10.5
(6.0.12.1056) on Windows and RealPlayer 10 (10.0.1.436) on Linux are
vulnerable.

The vendor has reported that the following products are vulnerable on
the following platforms:

Windows:
	RealPlayer 10.5 (6.0.12.1056 and below)
	RealPlayer 10
	RealOne Player V2
	RealOne Player V1
	RealPlayer 8
	RealPlayer Enterprise

Mac
	RealPlayer 10 (10.0.0.325 and below)
	RealOne Player

Linux
	RealPlayer 10
	Helix Player

V. WORKAROUND

There are no known workarounds for this vulnerability. Although .smil
files can be disassociated from RealPlayer, it is still possible to
cause these files to load with RealPlayer using other methods. One such
method is loading the file via one of the many ActiveX Controls that
RealPlayer contains. Any effective workaround would prevent RealPlayer
from functioning.

VI. VENDOR RESPONSE

A vendor advisory for this issue is available at:

   http://service.real.com/help/faq/security/050224_player

VII. CVE INFORMATION

The Common Vulnerabilities and Exposures (CVE) project has assigned the
names CAN-2005-0455 to these issues. This is a candidate for inclusion
in the CVE list (http://cve.mitre.org), which standardizes names for
security problems.

A remote attacker may execute arbitrary code on a vulnerable computer to gain unauthorized access.

This vulnerability is reported to exist in RealNetworks products for Microsoft Windows, Linux, and Apple Mac platforms.
