On-Demand Webcast: New Ponemon Study Reveals Disconnects in Building the Business Case for Data Protection Newly released research reveals that while C-level executives feel that good data protection efforts support organizational goals such as compliance, reputation management or customer trust, there is a lack of confidence in the ability to safeguard sensitive information.

PART I Critical Vulnerabilities Part I for this issue has been compiled by Josh Bronson at TippingPoint, a division of 3Com, as a by-product of that company's continuous effort to ensure that its intrusion prevention products effectively block exploits using known vulnerabilities. TippingPoint's analysis is complemented by input from a council of security managers from twelve large organizations who confidentially share with SANS the specific actions they have taken to protect their systems. A detailed description of the process may be found at http://www.sans.org/newsletters/cva/#process
Description: A zero-day vulnerability for multiple Adobe products is being actively exploited in the wild, and exploit code is publicly available. The vulnerability is in the Flash virtual machine's handling of invalid code. Both Adobe Acrobat and Adobe Reader are vulnerable. By enticing a user to open a malicious PDF or SWF file, an attacker can exploit this vulnerability in order to execute arbitrary code with the permissions of the currently logged-in user. Adobe is currently developing a patch for this issue, but updates are not yet available. The US-CERT reference below contains instructions for disabling vulnerable Adobe products. Note that the Flash 10.1 Release Candidate has been confirmed by Adobe not to be vulnerable to this issue.
Status: vendor confirmed, updates not available
Description: Microsoft Internet Explorer is susceptible to multiple vulnerabilities, including some that may lead to code execution. These vulnerabilities involve unspecified uninitialized memory corruption vulnerabilities. All of them are triggered only if a target is enticed to open a malicious web site. All of these vulnerabilities have been privately and responsibly disclosed to Microsoft.
Status: vendor confirmed, updates available
Description: Apple has recently released patches for multiple vulnerabilities in Apple Safari. Several of these may be exploited by an attacker in order to achieve code execution. The vulnerabilities are in Safari's handling of web-related content, so a user must be enticed to open a malicious web page in order to be affected by these vulnerabilities. Many of these vulnerabilities were reported to Apple through responsible disclosure by the Zero Day Initiative.
Status: vendor confirmed, updates available
Description: Internet Information Services (IIS), Microsoft's HTTP server, is vulnerable to a remote code execution vulnerability. By sending a malicious authentication token, an attacker can exploit this vulnerability in order to execute code with the permissions of the affected process. Note that IIS is only affected when the Extended Protection for Authentication feature of IIS is installed and enabled. This feature is not installed by default.
Status: vendor confirmed, updates available
Description: Microsoft Data Analyzer, which is used by Microsoft Excel for data analysis, contains a code execution vulnerability that could be triggered by enticing a target to visit a malicious page. The vulnerability is in an ActiveX control of the product.
Status: vendor confirmed, updates available
Description: HP OpenView, a product for monitoring and managing networks, is susceptible to two remote buffer overflow vulnerabilities. Both of these vulnerabilities can by triggered by an attacker by sending malicious HTTP requests to the jovgraph.exe CGI application. Successful exploitation can lead to remote code execution.
Status: vendor confirmed, updates available
Description: Google Chrome, a popular web browser, has released fixes for several reported bugs. Some of these bugs are related to sandbox escapes and memory corruption. These types of bugs often lead to code execution, but Google does release details about these vulnerabilities. Google Chrome is designed to automatically update itself in the background, so no user action should be required to acquire these fixes.
Status: vendor confirmed, updates available
Part II -- Comprehensive List of Newly Discovered Vulnerabilities from Qualys (www.qualys.com) This list is compiled by Qualys ( www.qualys.com ) as part of that company's ongoing effort to ensure its vulnerability management web service tests for all known vulnerabilities that can be scanned. As of this week Qualys scans for 9574 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
