A quiet week - and a sincere wish for a safe and prosperous 2009 for all our readers. Alan
@RISK is the SANS community's consensus bulletin summarizing the most important vulnerabilities and exploits identified during the past week and providing guidance on appropriate actions to protect your systems (PART I). It also includes a comprehensive list of all new vulnerabilities discovered in the past week (PART II).

Part I for this issue has been compiled by Rob King 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: Fujitsu-Siemens WebTransactions, part of the Fujitsu-Siemens openSEAS suite, is a popular enterprise middleware application that provides access to legacy or otherwise not web-enabled software via the web. It fails to properly sanitize user input in certain situations, leading to an arbitrary command execution vulnerability. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary commands with the privileges of the vulnerable process. Technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available.
Description: Trend Micro House Call is a popular online-based malware scanning service. Part of its functionality is provided by an ActiveX control. This control contains a memory corruption vulnerability. A specially crafted web page that instantiates this control could trigger this vulnerability, allowing an attacker to execute arbitrary code with the privileges of the current user. Some technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the affected control via Microsoft's "kill bit" mechanism. Note that this could impact normal application functionality.
Description: FreeSSHd is a free Secure Shell (SSH) server for Microsoft Windows. It also provides Secure File Transfer Protocol (SFTP) services. The SFTP server contains multiple buffer overflows in its handling of user commands. A logged-in user could trigger one of these vulnerabilities by sending an overlong command to the server. Successfully exploiting this code would allow an attacker to execute arbitrary code with the privileges of the vulnerable process. A proof-of- concept is publicly available for these vulnerabilities. Note that attackers must have valid authentication credentials to exploit this vulnerability.
Status: Vendor has not confirmed, no updates available.
Description: Chrome is a popular web browser from Google. It is reported to be vulnerable to a command injection vulnerability due to insufficient sanitization of "chomeHTML" URLs. However, other reports have indicated that this vulnerability may not be exploitable by remote users. Additionally, some reports have indicated that Microsoft Internet Explorer 8 Beta may be vulnerable when Google Chrome is installed. Proofs-of-concept are publicly available for this vulnerability, but no confirmation of exploitability.
Status: Vendor has not confirmed, no updates available.
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 5549 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
