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: Apple has released patches addressing multiple vulnerabilities in its Safari web browser. The vulnerabilities include use-after-free flaws in WebKit's implementation of the FrameOwner element, Scalar Vector Graphics (SVG) markers, DOM attribute copying, and implicitly defined styles for HTML. Other vulnerabilities listed by Apple include problems in underlying libraries like CoreGraphics that could be exploited via multiple vectors. By enticing a target to view a malicious site, an attacker could exploit these vulnerabilities in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: Foxit has released a patch addressing a buffer overflow vulnerability in its FoxitReaderOCX ActiveX control, which is included in its plugin for FireFox. By enticing a target to view a web site that instantiates this control and sends an overly long string to the strFilePath parameter of its OpenFile() method, an attacker can exploit this vulnerability in order to execute arbitrary code on the target's machine.
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 11861 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
