Both Microsoft Word and Firefox have newly discovered vulnerabilities that allow remote attackers to control the victims' computers - Word through a corrupted document and Firefox through a malicious web site. Neither vendor has released patches. It is a great time to remind you users never to open attachments unless you were expecting them from someone you know. There's really no security awareness defense against the Firefox vulnerability because many trusted sites are already infecting unsuspecting users. Alan P.S. The Virtualization Security Summit in Las Vegas ( http://www.sans.org/virtualization08_summit/) and the European SCADA Summit in Amsterdam ( http://www.sans.org/euscada08_summit/) were just posted today for registration.
@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: Microsoft Word contains a memory corruption vulnerability in its handling of unordered (bulleted) lists. A specially crafted Word document containing such a list could trigger this vulnerability. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary code with the privileges of the current user. Note that, on recent versions of Microsoft Office, Word documents are not opened upon receipt without first prompting the user. Several proofs-of-concept are publicly available for this vulnerability, as are several videos demonstrating the attack. Note that further details are unavailable - most importantly, it is unknown if other versions of Microsoft Office are affected. Note that the demonstration videos indicate that user interaction is required to exploit these vulnerabilities; this is unconfirmed.
Status: Vendor has not confirmed, no updates available.
Description: Mozilla Firefox contains an unspecified remote code execution vulnerability. A specially crafted web page could trigger this vulnerability, allowing an attacker to execute arbitrary code with the privileges of the current user. No details have been publicly released for this vulnerability, but these details could be obtained via source code analysis.
Status: Vendor confirmed, no updates available.
Description: Novell iPrint is a network printing system. Part of its client's functionality is provided by an ActiveX control. This control contains multiple vulnerabilities in its handling of various parameters. A specially crafted web page that instantiates this control could trigger one of these vulnerabilities. Successfully exploiting one of these vulnerabilities would allow an attacker to execute arbitrary code with the privileges of the current user. Some technical details for this vulnerability are publicly available.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the affected control via Microsoft's "kill bit" mechanism for CLSID "36723F97-7AA0-11D4-8919-FF2D71D0D32C". Note that this may affect normal application functionality.
Description: Opera is a popular cross-platform web browser. It contains multiple vulnerabilities in its handling of images, HTML frames, and certain characters in addresses. Successfully exploiting one of these vulnerabilities would allow an attacker to load images from non-authorized domains, obscure the current page address, or alter the contents of unrelated frames. Some technical details are publicly available for these vulnerabilities.
Status: Vendor confirmed, 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.
