Apple QuickTime and Blackberry users have critical problems to deal with.
@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).

Your Network Security Isn't Good Enough Anymore
Today's threats-and networks-are dynamic. Unfortunately most network security systems are not.
Join Martin Roesch, Founder and CTO of Sourcefire(r) and Creator of Snort(r), in a series of seminars, as he shows why network security must include full network visibility, relevant context, and automated impact assessment to be effective.

Part I for this issue has been compiled by Rohan Kotian 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: Apple QuickTime, a widely used media player, contains a heap-based buffer overflow while parsing a malformed .PICT image. The specific error is caused while parsing a PICT image with a poly tag 0x77. The application, while allocating tag data doesn't use the 16-bit length properly thus leading to a heap-based buffer overflow condition. Successful exploitation might lead to arbitrary code execution under the context of the logged in user. User interaction is required in that the victim must either visit a malicious site or open a malicious file.
Status: Vendor confirmed, updates available.
Description: The Research In Motion BlackBerry is a popular mobile telephone and messaging device. The BlackBerry handheld devices are integrated with an enterprise's messaging infrastructure through BlackBerry Enterprise Server. This server software and the professional software version of BlackBerry have unspecified vulnerabilities in the BlackBerry Attachment Service, a service used to view different file formats. The errors are within the PDF distiller component of the Attachment Service. A specially crafted PDF file opened on BlackBerry could trigger this vulnerability and cause memory corruption. Successful exploitation can lead to arbitrary code execution. Note that a user must first open the PDF on a BlackBerry mobile device for exploitation to occur. No technical details publicly available.
Status: Vendor confirmed, updates available.
Description: Novell GroupWise is Novell's enterprise groupware solution. Novell GroupWise WebAccess and Internet Agent have been identified with multiple vulnerabilities. The first is a cross-site scripting vulnerability in GroupWise WebAccess via unfiltered style expressions. This exploit if successful could be used for arbitrary code injection. The second vulnerability is in the way GroupWise WebAccess blocks scripting. Successful exploitation might allow an attacker access to authenticated user's account. The third issue is caused due to inputs not being properly sanitized by GroupWise WebAccess. This could allow an attacker to deface the login page, thereby preventing users from logging into WebAccess. The fourth vulnerability is an unspecified error in the way GroupWise Internet Agent handles certain SMTP requests. Successful exploitation might lead to arbitrary code execution. The fifth issue is due to vulnerability within the session management mechanisms in the GroupWise WebAccess. This could potentially allow an attacker to gain access to an authenticated user's account. The sixth issue is in the way Novell GroupWise Internet Agent handles certain email addresses in the SMTP protocol. Successful exploitation might lead to arbitrary code execution with system privileges. Some technical details are publicly available.
Status: Vendor confirmed, updates available.
Description: ImageMagick is an open software suite of graphics manipulation utilities for several operating systems. It has an integer overflow vulnerability while processing a specially crafted malformed TIFF file. The specific vulnerability is the integer overflow error in the XMakeImage()" function in xwindow.c. By tricking the user to open a malicious TIFF file, an attacker might crash the affected application or execute arbitrary code. Technical details for this vulnerability are available via source code analysis.
Status: Vendor confirmed, updates available.
Description: CiscoWorks Common Services (CS) is a set of management services used by other CiscoWorks applications to share a common model for data storage, user access privileges, etc. It has a directory traversal vulnerability within the TFTP service. This service is enabled by default. This could allow an attacker to access or modify the application and host operating system files. Authentication is not required to carry out this attack.
Status: Vendor has 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 7041 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
