The Microsoft RPC problem is the big one - lots of exploits. If you haven't fixed it, might be good to act quickly. 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: Last week, Microsoft issued an out-of-cycle patch for a remote code execution vulnerability in various versions of Microsoft Windows; the initial announcement was covered in that week's @RISK. Further details are now available for this vulnerability. The flaw originates from a flaw in the Microsoft Windows Server Service, which exports a Remote Procedure Call (RPC) interface. A flaw in one of the exported procedures could allow an attacker to execute arbitrary code with the privileges of the vulnerable process (SYSTEM). The vulnerable procedures do not require authentication on versions of Microsoft Windows other than Windows Vista and Windows Server 2008. Microsoft believes that this vulnerability is being actively exploited in the wild. Proofs-of-Concept for this vulnerability are now publicly available.
Status: Vendor confirmed, updates available. Users are urged to patch as quickly as possible.
Description: OpenOffice.org is a popular open source office suite. It is installed by default on numerous Unix- and Linux-based operating systems, and is commonly installed on Microsoft Windows and Apple Mac OS X systems. It contains multiple flaws in its handling of Windows Metafile (WMF) and Enhanced Metafile (EMF) image files. A specially crafted WMF or EMF image could trigger one of several heap-based buffer overflows in OpenOffice.org. Successfully exploiting one of these vulnerabilities would allow an attacker to execute arbitrary code with the privileges of the current user. Depending upon configuration, malicious documents may be opened upon receipt without first prompting the user. Details on these vulnerabilities is available via source code analysis. The commercial fork of OpenOffice.org, StarOffice, is presumed vulnerable as well.
Status: Vendor confirmed, updates available.
Description: Opera is a popular cross-platform web browser. It contains multiple vulnerabilities in its handling of JavaScript URLs and history entries. Entries placed in the browser's history are not properly sanitized, nor are JavaScript URLs. A specially crafted web page could trigger this vulnerability to execute arbitrary JavaScript code in a higher security context than would otherwise be allowed. Some technical details for these vulnerabilities are publicly available.
Status: Vendor confirmed, updates available.
Description: Adobe PageMaker is a popular desktop publishing application. It contains multiple buffer overflows in its handling of PMD (PageMaker) files. A specially crafted PMD file could trigger one of these buffer overflows, allowing an attacker to execute arbitrary code with the privileges of the current user. Depending upon configuration, malicious files may be opened upon receipt without first prompting the user. Some technical details are publicly available for these vulnerabilities.
Status: Vendor confirmed, updates available. A third vulnerability is confirmed, but unpatched.
Description: Sun Java Web Start is part of Sun's Java Runtime Environment, and allows Java applications to be launched from a web browser. It contains an input validation error in its handling of Web Start requests. A specially crafted web page could exploit this vulnerability to exploit arbitrary commands with the privileges of the current user. Technical details for this vulnerability are publicly available, but are unconfirmed. The Sun Java Runtime Environment is installed by default on numerous Unix- and Linux-based operating systems as well as Apple Mac OS X. It is often installed on Microsoft Windows systems.
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.
