Two security products (Trend Micro and ClamAV) have critical security vulnerabilities this week, as do Apple OS X, Adobe Flash, and an HP component used for software deployment.
An end-of-year note for people who do or buy penetration testing: The character of attacks has changed this year, rendering most penetration testers who learned their skills more than eighteen months ago essentially obsolete. And the changes are continuing. If you put yourself forward as a penetration tester, make sure you have skills to test vulnerability to today's attacks rather than the attacks of 2005 and 2006. The best penetration testers in the world will be coming to Las Vegas in March to share techniques. http://www.sans.org/info/21218

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: Adobe Flash Player is the most popular platform for rich internet content. The Adobe Flash Player web browser plugin is bundled with Microsoft Windows, Apple Mac OS X, and various Unix and Linux-based operating systems. The Flash plugin contains multiple vulnerabilities in its handling of Flash content and network requests. A specially crafted web page with embedded Flash content could exploit one of these vulnerabilities to allow an attacker to execute arbitrary code with the privileges of the current user, perform cross site scripting attacks, or execute other attacks. Note that Flash content is generally loaded automatically upon receipt, therefore no user interaction other than viewing a malicious web page would be necessary to exploit these vulnerabilities. Some technical details are publicly available for these vulnerabilities.
Status: Adobe confirmed, updates available.
Description: ServerProtect is an anti-malware solution from Trend Micro. ServerProtect exports a Remote Procedure Call (RPC) interface. This interface provides various filesystem manipulation procedures that may be called without authentication. Calling these procedures would allow an attacker to arbitrary modify system files and configuration with the privileges of the vulnerable process (usually SYSTEM). Full technical details are publicly available for this vulnerability.
Status: Trend Micro confirmed, updates available.
Description: HP-UX is Hewlett-Packard's UNIX-derived operating system. HP-UX's 'swagentd' component is used for software deployment and other tasks. It exports a Remote Procedure Call (RPC) interface accessible to other systems. A specially crafted call to this RPC interface could trigger a buffer overflow. Successfully exploiting this buffer overflow would allow an attacker to execute arbitrary code with the privileges of the vulnerable process. Some technical details are publicly available for this vulnerability.
Status: Hewlett-Packard confirmed, updates available. Users can mitigate the impact of this issue by blocking access to TCP and UDP port 2121 at the network perimeter, if possible.
Description: ClamAV is a popular multiplatform antivirus solution. Executable packers are often used to obfuscate malware. ClamAV contains multiple vulnerabilities in its handling of packed executables. A specially crafted packed executable could trigger one of these vulnerabilities, and allow an attacker to execute arbitrary code with the privileges of the vulnerable process. Note that in situations where ClamAV is used to scan email or automatically scan files, no user interaction would be required to exploit this vulnerability. In these cases, email transiting the server or files otherwise sent to the vulnerable system would be sufficient to exploit this vulnerability. Note that full technical details are available for this vulnerability via source code analysis.
Status: ClamAV confirmed, updates available.
Description: Apple Mac OS X contains multiple vulnerabilities in a variety of subsystems. Some vulnerabilities stem from known vulnerabilities in bundled third-party software, while others are endemic. The severity of these vulnerabilities range from arbitrary code execution with the privileges of the current user or of a system process, to arbitrary file overwrites, to cross site scripting attacks. Some technical details are publicly available for several of these vulnerabilities.
Status: Apple confirmed, updates available.
Description: The Yahoo! Toolbar is a web browser toolbar from Yahoo! that makes it easier to access certain Yahoo! services. Part of the toolbar's functionality is provided by an ActiveX control. This control contains a buffer overflow vulnerability. A specially crafted web page that instantiates this control could trigger this vulnerability, and allow an attacker to execute arbitrary code with the privileges of the current user. The Yahoo! Toolbar is installed as part of some software packages, and may be installed by default by certain systems integrators.
Status: Yahoo! has not confirmed, no updates available. Users can mitigate the impact of this vulnerability by disabling the control via Microsoft's __kill bit__ mechanism.
Description: IBM Lotus Domino is an IBM collaboration solution. Part of its web-based functionality is provided by an ActiveX control. This control contains a buffer overflow vulnerability in the handling of its __General_ServerName__ property. A specially crafted web page that instantiates this control and sets this property could exploit this buffer overflow. Successfully exploiting this buffer overflow would allow an attacker to execute arbitrary code with the privileges of the current user. Some technical details and a proof-of-concept are publicly available for this vulnerability.
Status: IBM has not confirmed, no updates available. Users can mitigate the impact of this vulnerability by disabling the vulnerable control via Microsoft's __kill bit__ mechanisms for CLSID __E008A543-CEFB-4559-912F-C27C2B89F13B__. Note that this may affect normal application functionality.
Description: Novell GroupWise is Novell's enterprise groupware solution. GroupWise contains a flaw in its handling of email with embedded HTML. A specially crafted email message containing and overlong __src__ parameter to an __<img>__ tag could trigger a buffer overflow vulnerability. Successfully exploiting this vulnerability would allow an attacker to execute arbitrary code with the privileges of the current user. Full technical details and multiple proofs-of-concept are publicly available for this vulnerability. This vulnerability is exploitable only if the user has the __HTML Preview__ option enabled and responds to or forwards a malicious email; simply reading a malicious message is insufficient to exploit this vulnerability.
Status: According to reports, Novell has silently patched this vulnerability.
Description: Opera is a popular cross-platform web browser. It contains multiple vulnerabilities. Most vulnerabilities are limited to cross site scripting attacks or information disclosure vulnerabilities, but an undisclosed error in the handling of Transport Layer Security (TLS, sometimes known as SSL version 3) certificates could lead to arbitrary code execution with the privileges of the current user.
Status: Opera confirmed, updates available.
Description: Open File Manager (OFM) is a enterprise backup management solution from St. Bernard. OFM exports a network-accessible service. This service contains a buffer overflow vulnerability. A specially crafted call to this service could exploit this buffer overflow and allow an attacker to execute arbitrary code with the privileges of the vulnerable process (usually SYSTEM). Some technical details are publicly available for this vulnerability.
Status: St. Bernard confirmed, updates available.
Description: iMesh is a popular music and video sharing application. Part of its functionality is provided by the __IMWebControl__ ActiveX control. This control contains a buffer overflow vulnerability. A malicious web page that instantiates this control could trigger this buffer overflow and allow an attacker to execute arbitrary code with the privileges of the current user. A proof-of-concept and full technical details are publicly available for this vulnerability.
Status: iMesh has not confirmed, no updates available. Users can mitigate the impact of this vulnerability by disabling the vulnerable control via Microsoft's __kill bit__ mechanism, using CLSID __7C3B01BC-53A5-48A0-A43B-0C67731134B9__. Note that this may impact normal application functionality.
