PART I Critical Vulnerabilities Part I for this issue has been compiled by Josh Bronson at TippingPoint, a division of HP, 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/risk/#process
Description: Microsoft has released a patch addressing a vulnerability in Microsoft Internet Explorer. The vulnerability exists within the Windows MSADO component, which is responsible for providing an interface to data access services. An attacker can exploit this vulnerability by enticing the target to navigate to a malicious web site, potentially resulting in arbitrary code execution.
Status: vendor confirmed, updates available
Description: HP OpenView Network Node Manager (NNM), part of the OpenView suite, provides an interface for graphically viewing and managing networks. Part of the functionality of NNM is implemented with CGI (Common Gateway Interface) programs. HP has recently released patches for multiple vulnerabilities within these programs. The vulnerabilities include a buffer overflow in ovutil.dll, called by jovgraph.exe, due to user-controlled value printed in an sscanf to a fixed-length buffer, and similar problems with ovas.exe and nnmRptConfig.exe. An attacker can send malicious requests in order to exploit these vulnerabilties, which could result in arbitrary code execution.
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 10794 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
