A nice week! Nothing extremely critical. 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).
************* Sponsored By SANS Forensics Summit ***********************
Join other professionals at the Forensics & Incident Response Summit October 13-14. Discuss the latest processes and technologies for effective incident response and mitigation, forensic analysis, and recovery as a result of a data breach in any size organization. Hear what your peers are doing in this space and what the best tools are. http://www.sans.org/info/32243

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: JustSystems Ichitaro is the second most popular word processing application in Japan, and is popular throughout Asia. It contains a remote code execution vulnerability in its handling of documents. A specially crafted document could trigger this vulnerability, allowing an attacker to execute arbitrary code with the privileges of the current user. Depending upon configuration, such documents may be opened by the vulnerable application upon receipt, without first prompting the user. According to reports, this flaw is being actively exploited in the wild.
Status: Vendor confirmed, no updates available.
Description: Novell iPrint is a popular network document printing solution. Part of its client's functionality is implemented as an ActiveX control. This control contains multiple vulnerabilities in its handling of a variety of parameters and methods. A specially crafted web page that instantiates this control could trigger one of these vulnerabilities, allowing an attacker to execute arbitrary code with the privileges of the current user. Additional vulnerabilities range from arbitrary file overwrites to information disclosure. Technical details are publicly available for these vulnerabilities.
Status: Vendor confirmed, updates available. However, it is thought that the available updates to not address all issues. 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 Anzio Web Print Object (WePO) is a popular "push" printing solution. Its functionality is provided by an ActiveX control. This control contains a buffer overflow in its handling of its "mainurl" parameter. A specially crafted web page that instantiates this control could trigger this buffer overflow, allowing an attacker to execute arbitrary code with the privileges of the current user. Technical details are publicly available for this vulnerability. A simple proof-of-concept is also publicly available for this vulnerability.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the affected control using Microsoft's "kill bit" mechanism using CLSID "4CE8026D-5DBF-48C9-B6E9-14A2B1974A3D". Note that this will affect normal application functionality.
Description: LibTIFF is a decoding and manipulation library for the Tagged Image File Format (TIFF), a popular image format. It contains a flaw in its decoding of compressed TIFF data. A specially crafted TIFF file could trigger this flaw, leading to a buffer underflow condition. It is believed that this flaw could potentially lead to remote code execution with the privileges of the vulnerable process, though this is not confirmed. Full technical details for this vulnerability are publicly available via source code analysis.
Status: Vendor has not confirmed, no updates available. Some distributors have patched their systems.
Description: OpenOffice.org is a popular cross-platform free office suite, installed by default on numerous Linux- and Unix-based operating systems. It is also available for Microsoft Windows and Mac OS X. It contains a flaw in its handling of certain constructs in OpenOffice.org documents. A specially crafted document could trigger this flaw, leading to a misallocation of memory. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary code with the privileges of the current user. Note that only OpenOffice.org on 64-bit platforms is vulnerable. Note that, depending upon configuration, documents may be opened by the vulnerable application upon receipt, without first prompting the user. Full technical details for this vulnerability are available via source code analysis.
Status: Vendor confirmed, updates available.
Description: Red Hat, a major north American Linux vendor, and Fedora, a popular free Linux distribution sponsored by Red Hat, suffered a security breach. The attacker was able to sign and possibly modify several packages for these operating systems, including the OpenSSH server package. It is not currently believed that the attacker was able to inject these packages into the automated update stream, but Red Hat is advising users to double-check their systems to ensure that no tainted packages were installed. Details on how to verify systems is available in the links below.
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.
