Apple's QuickTime is ubiquitous - on both Windows and Macs -- installed automatically with LOTS of programs. And attackers think of programs like QuickTime as the "sweet spot" for easy penetration. So the critical vulnerabilities announced in QuickTime really matter. 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).

SANS Real-time Adaptive Security White Paper
Real-time Adaptive Security is the next step beyond an IPS implementation. It gives you full network visibility, provides context around events so you know which ones to investigate first, reduces your false positives dramatically, offers automated impact assessment, introduces automated IPS tuning, and more. Let SANS tell you how. http://www.sans.org/ info/37493"> http://www.sans.org/ info/37493

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: QuickTime is Apple's streaming media framework for their Mac OS X and Microsoft's Windows operating systems. It contains multiple vulnerabilities in its handling of a variety of media files and Real Time Streaming Protocol (RTSP) URLs. A specially crafted media file or URL 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. Note that, by default, most QuickTime-supported media files are opened upon receipt, without first prompting the user. QuickTime is installed by default on all Apple Mac OS systems, and is installed as part of a variety of Apple products for Microsoft Windows, including iTunes.
Status: Vendor confirmed, updates available.
Description: AppStream is a popular enterprise application and data streaming application from Symantec. Part of its functionality is provided by an ActiveX control. This control contains multiple vulnerabilities in its handling of a variety of methods. A specially crafted web page that instantiated this control could exploit one of these vulnerabilities to execute arbitrary code with the privileges of the current user. Some technical details for these vulnerabilities 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 using CLSID "3356DB7C-58A7-11D4-AA5C-006097314BF8". Note that this could affect normal application functionality.
Description: Fujitsu Systemcast Wizard Lite is a software setup component and part of the PRIMEQUEST software suite from Fujitsu. It contains a buffer overflow vulnerability in its handling of Pre-Execution Environment (PXE) requests. A specially crafted request could trigger this buffer overflow. Successfully exploiting this buffer overflow would allow an attacker to execute arbitrary code with the privileges of the vulnerable application (often SYSTEM). Full technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available.
Description: Ralink is a popular manufacturer of wireless network interface devices and chipsets. Several of its drivers, for multiple platforms, are reported to be vulnerable to integer overflows in their processing of wireless network data. A specially crafted 802.11 (WiFi) network frame could trigger one of these vulnerabilities. Successfully exploiting one of these vulnerabilities would allow an attacker to execute arbitrary code with kernel-level privileges. The attacker need not be a member of the same wireless network as the victim, but merely needs to be within wireless networking range. Some technical details are publicly available for this vulnerability. Note that this vulnerability has not yet been confirmed.
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.
