Vulnerable: All versions.
Discovered by: William Borskey wborskey (at) gmail (dot) com [email concealed]
Discussion:
The mail application that ships with the iPod/iPhone does not validate SSL
certificates. A malicious user can use software such as ettercap-ng to sniff
email passwords without the application warning the victim that the

Package : htmldoc
Date : September 11, 2009
Affected: 2009.0, 2009.1, Corporate 4.0
_______________________________________________________________________
Problem Description:
A security vulnerability has been identified and fixed in htmldoc:
Buffer overflow in the set_page_size function in util.cxx in HTMLDOC
1.8.27 and earlier allows context-dependent attackers to execute
arbitrary code via a long MEDIA SIZE comment. NOTE: it was later
reported that there were additional vectors in htmllib.cxx and
ps-pdf.cxx using an AFM font file with a long glyph name, but these
vectors do not cross privilege boundaries (CVE-2009-3050).
This update provides a solution to this vulnerability.

CVE-2009-3077
– Affected Vendors:
Mozilla Firefox
– Affected Products:
Mozilla Firefox 3
– TippingPoint(TM) IPS Customer Protection:
TippingPoint IPS customers have been protected against this
vulnerability by Digital Vaccine protection filter ID 8442.
For further product information on the TippingPoint IPS, visit:
http://www.tippingpoint.com
– Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Mozilla Firefox. User interaction is
required to exploit this vulnerability in that the target must visit a
malicious page.
The specific flaw exists during the redrawing of tree columns contained
within a XUL document. Due to the reuse of a previously freed object,
attacker controlled memory can be executed. Successful exploitation of
this vulnerability can lead to remote compromise of the affected system
under the credentials of the currently logged in user.

IBM Lotus Notes 8.5 RSS Widget Privilege Escalation
scip AG Vulnerability ID 4021 (09/08/2009)
http://www.scip.ch/?vuldb.4021
I. INTRODUCTION
Lotus Notes is a client-server, collaborative application developed and
sold by IBM Software Group.
More information is available on the official product web site at the
following URL:
http://www.ibm.com/software/lotus/products/notes/
II. DESCRIPTION
Marc Ruef at scip AG found a design vulnerability in the current Release
8.5.
The product provides some widgets which can be added and enabled by the
user. One of those widgets provide a simple RSS reader.
This reader downloads the RSS file, extracts the items and saves them
locally as HTML files.
The interpretation and display of the RSS items is handled by the
Internet Explorer regarding the applied security zone.
III. EXPLOITATION
No exploitation is required. A malicious RSS feed may contain script
data or embedded objects.
IV. IMPACT
The RSS items are handled like web documents which introduces the
possibility of running script code or to embed multimedia objects (e.g.
Flash or movies).
Because locally saved files run in the Local Zone of the Internet
Explorer some privilege escalation is possible.
V. DETECTION
It may be possible to identify malicious RSS feeds if they contain
script code or embedded objects.
VI. SOLUTION
IBM has been informed immediately. They are able to address this
vulnerability with a hotfix.
VII. VENDOR RESPONSE
The vendor verified the existence of the issue and addressed it as soon
as possible with a hotfix. Unfortunately most of the communication
bypassed us and were forced to ask for the current status several times.
Our last request of the current status at 08/24/2009 were unanswered.

* SaveVTask()
Evolution TNEF Attachment decoder plugin
The plugin is started on e-mail attachments that have a MIME type of either application/vnd.ms-tnef or application/ms-tnef. It creates a temporary directory under ~/.evolution/cache/tmp using the format tnef-attachment-XXXXXX. The TNEF attachment is saved as .evo-attachment.tnef.
The saved file is parsed by TNEFParseFile(), the result is stored in a struct of the type TNEFStruct. This struct is passed to the function processTnef(), which tries to extract all relevant data and attachments from the TNEF stream. Each relevant part of the TNEF stream is stored within the previously created temporary directory that are made available to the end user as separate e-mail attachments.
yTNEF
yTNEF processes TNEF files in a similar manner. It receives a file name from the command line, calls TNEFParseFile() that creates a struct TNEFStruct after which ProcessTNEF() is called. If ProcessTNEF() finds attachments it can process, these attachments will be saved locally. The ProcessTNEF() function is almost the same as the processTnef() function of the Evolution plugin.
Directory Traversal
If a TNEF file is processed, both yTNEF and the Evolution plugin will save certain types of TNEF structures. Special processing functions are available for Contacts, Tasks & Appointments. These functions are called if the Message Class is set to a certain value.
There is also code that treats TNEF structures with the Message Class set to IPM.Microsoft Mail.Note. In the Evolution plugin, this code is never called as the global variable saveRTF is set to zero. In case of yTNEF this global variable is controlled by the command line.
After the structures mentioned before have been processed, all other attachments are also saved locally. The file names used to save the attachments are obtained from the TNEF data. In case of normal attachments, the code first looks if the TNEF data contains MAPI properties and if so, it will look for specific properties. If these exists, a file name is extracted from these properties. If the properties do not exist, the attachment’s title is used. This title is also set through a TNEF structure. If this title is also not available, a default file name will be used instead.
Before a new file is created, all spaces within the file name are replaced with the underscore character. No additional sanitation is performed on the file name. Because of this, it is possible to traverse outside of the temporary directory and create or overwrite any file with the privileges of the target user. This allows an attacker to execute arbitrary code for example by overwriting ~/.bashrc.
Buffer Overflow
eside the directory traversal, it is also possible to trigger a buffer overflow by supplying an overly long file name. This is possible, because the file name is copied in a fixed size buffer (256 bytes). In the Evolution plugin, this triggers a buffer overflow on the heap. In case of yTNEF the file name is copied in a buffer on the stack, thus allowing for a stack-based buffer overflow to occur.

Beware of Googling (or indeed Yahooing or Binging or using any other internet search engine) for information about something called “Facebook Fan Check Virus”, as you’re likely to end up on a website hosting malicious code.
The phrase “Facebook Fan Check Virus” is currently a hot trending topic on Google, with many net users searching for information.
However, hackers have set up websites pretending to be about the “Facebook Fan Check Virus”, but which really host fake anti-virus software which display bogus warnings about the security of your computer in an attempt to get you to install fraudulent software and cough-up your credit card details.

Google SketchUp is prone to a remote buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied input.
Attackers may exploit this issue to execute arbitrary code in the context of the application. Failed attacks will cause denial-of-service conditions.
Google SketchUp 7.0.10247 is vulnerable; other versions may also be affected.
Solution:
Currently we are not aware of any vendor-supplied patches.
Pidgin Libpurple is prone to multiple denial-of-service vulnerabilities.
Successful exploits will crash the application, denying service to legitimate users.
Pidgin Libpurple versions 2.6.1 and prior are affected.

Microsoft IIS is prone to a remote stack-based buffer-overflow vulnerability affecting the application’s FTP server.
An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
This issue affects the following:
IIS 5.0
IIS 5.1
IIS 6.0 (denial of service only)
IIS 7.0 (denial of service only)
Please note that Microsoft IIS 7.0 with FTP Service 7.5 is not affected.
Other versions may also be affected.
NOTE: This issue cannot be exploited to execute arbitrary code on IIS 6.0 or 7.0.
NOTE (September 1, 2009): This issue can be exploited to execute arbitrary code with SYSTEM-level privileges on IIS 5.0.
