Novell and RedHat users have substantial challenges to deal with this week. But look through the 52 new Cross Platform vulnerabilities and the 41 Web application vulnerabilities in Part II just to verify whether your software is included. That will remind you to establish a patching regimen for your non-standard software. 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).

The Forensics & Incident Response Summit October 13-14 is a user-to-user, non-commercial conference on What Works in Forensics & Incident Response. It is the only place where you can learn methods for ensuring practical and accurate incident response and computer forensics for incidents, and hear users share the lessons they've learned. http://www.sans.org/info/32684

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 eDirectory is Novell's Lightweight Directory Access Protocol (LDAP) directory server. It contains multiple vulnerabilities in its handling of user input, including several buffer overflows and memory corruption vulnerabilities. A specially crafted request could trigger one of these vulnerabilities, allowing an attacker to execute arbitrary code with the privileges of the vulnerable process. Several cross-site-scripting, denials-of-service and other issues were addressed in this update. Some technical details are publicly available for these vulnerabilities.
Status: Vendor confirmed, updates available.
Description: Red Hat Directory Server is Red Hat's Lightweight Directory Access Protocol (LDAP) directory server. It contains multiple buffer overflow and cross-site-scripting vulnerabilities in its web interface. Successfully exploiting one of these vulnerabilities would allow an attacker to execute arbitrary code with the privileges of the vulnerable process (usually root). Additionally, several vulnerabilities in the processing of LDAP requests can lead to denial-of-service conditions. Red Hat Directory Server is the commercialized version of the Fedora Directory Server, which is open source. Therefore, technical details for these vulnerabilities may be publicly available via source code analysis. Note that Red Hat Directory Server is available for multiple operating systems.
Status: Vendor confirmed, updates available.
Description: Novell Forum is a popular team conferencing solution. It contains an input validation vulnerability in its handling of user input. A specially crafted request can bypass input validation and allow the injection of arbitrary Tcl programming language commands. These commands would be executed within the context of the vulnerable process, and allow arbitrary code execution with the privileges of the vulnerable process. Some technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available.
Description: Novell iPrint is a popular enterprise printing solution. Part of its client's functionality is provided by an ActiveX control. This control contains a buffer overflow in its handling of several methods. A specially crafted web page that instantiates this control and calls these methods could trigger this buffer overflow. Successfully exploiting this buffer overflow would allow an attacker to execute arbitrary code with the privileges of the current user. Technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the affected control via Microsoft's "kill bit" mechanism. Note that this will affect normal application functionality.
Description: The Ultra Office ActiveX control is used to integrate web and other applications with Microsoft Office. It contains multiple vulnerabilities in its handling of several methods. A specially crafted web page that instantiates this control could exploit one of these vulnerabilities to overwrite arbitrary files on a victim's system, or execute arbitrary code with the privileges of the current user. Full technical details and proofs-of-concept are available for these vulnerabilities.
Status: Vendor has not confirmed, no updates available.
Description: Multiple vulnerabilities have been discovered in multiple VMware products. Several products use ActiveX controls that have potential remote code execution vulnerabilities; a malicious web page that instantiates one of these controls could exploit one of these vulnerabilities to potentially execute arbitrary code with the privileges of the current user. Additionally, several products have been shown to use older versions of various libraries that are themselves vulnerable to a variety of attacks, most notably, libpng. Various other denial-of-service vulnerabilities and information disclosure vulnerabilities have been discovered.
Status: Vendor confirmed, updates available.
Description: Libpurple is a library implementing the Microsoft Network (MSN) Messenger protocol, which is used for instant messaging. Libpurple's implementation of this protocol is used by numerous clients, including Pidgin and Audium. The library contains multiple integer overflows in its processing of messages; a specially crafted message could trigger one of these overflows, allowing an attacker to execute arbitrary code with the privileges of the current user. Note that Pidgin is installed by default on numerous Linux, Unix, and Unix-like operating systems, and Audium is a popular instant messaging application for Apple Mac OS X. Other applications using this library may also be vulnerable. Because this library is open source, full technical details are publicly available via source code analysis.
Status: Vendor 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.
