Novell, Firefox, McAfee and SonicWall users all need to implement updates this week. This week's list illustrates how the number of critical vulnerabilities, found outside the traditional Windows and UNIX operating systems and services, is growing. Many of this week's affected vendors have automated update service, but you might be surprised by the number of companies - such as back-up vendors - that still expect users to check their web site to find out whether vulnerabilities have been discovered and to get patches.

@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: Novell Client Trust is a Novell mechanism for client authentication, used by a variety of Novell products. A specially crafted request to this service could trigger a buffer overflow in a string copy operation. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary code with the privileges of the vulnerable process. Some technical details for this vulnerability are publicly available. Note that this product may be used by several Novell products. Currently, Novell BorderManager is confirmed as vulnerable.
Status: Novell confirmed, updates available. Users can mitigate the impact of this vulnerability by blocking access to UDP port 3024 at the network perimeter, if possible.
Description: McAfee E-Business Server is an enterprise encryption and data sharing application. This product contains a flaw in its handling of authentication packets. A specially-crafted authentication packet could trigger an integer overflow vulnerability. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary code with the privileges of the vulnerable process. Note that versions of the product for Microsoft Windows appear to be unaffected by this vulnerability.
Status: McAfee confirmed, updates available.
Description: The SonicWALL VPN client, used to connect to SonicWALL VPN servers, installs an ActiveX component. This component contains multiple vulnerabilities in various exported methods. Several methods contain buffer overflow vulnerabilities, while another method contains an arbitrary file deletion vulnerability. A malicious web page that instantiates this control and exploits one of these vulnerabilities would be able to execute arbitrary code with the privileges of the current user, or delete arbitrary files. Proofs-of-concept are available for several of the vulnerabilities, as are technical details.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the affected control via Microsoft(tm)s __kill bit__ mechanism, for CLSID 6EEFD7B1-B26C-440D-B55A-1EC677189F30.
Description: Mozilla Firefox contains a vulnerability in its handling of JavaScript. A specially crafted web page could bypass domain restrictions an allow an attacker to execute arbitrary JavaScript in a security domain different from that in which it was loaded. This could allow an attacker to alter the user interface or potentially execute arbitrary code with the privileges of the current user. Some technical details and a proof-of-concept are available for this vulnerability. Additionally, technical details may be available via source code analysis. Other Mozilla products, such as Thunderbird and SeaMonkey may also be affected.
Status: Mozilla has not confirmed, no updates available.
Description: Oracle E-Business Suite is a collection of Oracle(tm) enterprise applications. This application contains a vulnerability in its __okxLOV.jsp__ web page. A specially crafted request to this page would allow an attacker to execute arbitrary SQL code in the context of the vulnerable application. This could allow the attacker to alter the database or disclose other information. Additionally, the attacker may leverage this vulnerability to exploit an otherwise local vulnerability in the database.
Status: Oracle confirmed, updates available.
Description: The Macrovision InstallShield product allows software vendors to automatically verify installation targets on various criteria. This product provides its services via an ActiveX control. Several methods of this control allow for arbitrary file download and execution. A malicious web page that instantiated this control could use these methods to execute arbitrary code on a vulnerable system with the privileges of the current user. Note that the control does alert the user when it downloads files, and the user has the option to abort the download, but the option exists only as long as the download is occurring. Once the file has been downloaded, there is no opportunity to abort. This product is often installed by third parties, therefore, a user may be unaware that the vulnerable control is installed.
Status: Macrovision confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the vulnerable control via Microsoft(tm)s __kill bit__ mechanism for CLSID E9880553-B8A7-4960-A668-95C68BED571E.
Description: HP OpenView Radia Integration Server is the configuration management application of HP(tm)s OpenView suite. This product contains a vulnerability in its handling of requests to its built in web server. A request to this web server containing a specially crafted path would allow an attacker to view the contents of arbitrary files on the system. This service may run with administrative privileges, allowing the attacker to view all files on the system. Some technical details are available for this vulnerability.
Status: HP confirmed, updates available. Users can mitigate the impact of this vulnerability by blocking access to TCP port 3465 at the network perimeter, if possible.
Description: Symantec Altris is an operating system deployment solution for enterprises. The PXE component of this system contains a Trivial File Transfer Protocol (TFTP) server that allows clients access to files on the server. This server contains a directory traversal vulnerability. A specially crafted request to this server would allow an attacker to download any file accessible to the server. Since the server usually runs with SYSTEM privileges, this would be any file on the system. Some technical details are available for this vulnerability. Note that TFTP does not support authentication; therefore no authentication is necessary to exploit this vulnerability.
Status: Symantec confirmed, updates available. Users can mitigate the impact of this vulnerability by blocking access to UDP port 69 at the network perimeter, if possible.
Description: ACDSee is a popular image viewing application for Microsoft Windows. It contains several vulnerabilities in the processing of various file formats. A specially crafted PSP image file or LHA archive could trigger a buffer overflow, and allow an attacker to execute arbitrary code with the privileges of the current user. Depending on configuration, the affected file formats may be opened automatically by ACDSee. Note that the LHA parsing flaw is not present in the default configuration of ACDSee.
Status: ACDSee 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.
