Part I for this issue has been compiled by Josh Bronson at TippingPoint, a division of HP, 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/risk/#process
Description: Mozilla has released patches addressing multiple vulnerabilities in its Firefox web browser; Thunderbird, its email and usenet client; and SeaMonkey, its internet application suite. The issues included unspecified memory safety problems in Firefox's browser engine, dangling pointers, and two issues with the WebGLES library used by Firefox. It is likely that at least some of these issues can be used by an attacker to execute arbitrary code on a target's machine. Firefox has specifically mentioned that the last two issues with WebGL, an interface to OpenGL available in HTML5, could be used for code execution.
Status: vendor confirmed, updates available
Description: Google has released a patch addressing multiple security vulnerabilities in its Chrome web browser. Details are scarce on the vulnerabilities, but this is a particularly large patch with sixteen vulnerabilities rated "High" by Google. Vulnerabilities rated "High" are typically issues with stale pointers, buffer overflows, and other issues with memory corruption. By enticing a target to view a malicious page, an attacker can exploit vulnerabilities like these in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: IBM has released a patch addressing security vulnerabilities in Rational System Architect, a tool used to model business processes and systems. The vulnerabilities are exposed via the ActiveX controls actbar.ocx and actbar2.ocx, which can be instantiated from Internet Explorer. The Save(), SaveLayoutchanges(), SaveMenuUsageData(), and SetLayoutData() methods are all vulnerable due to a design flaw in the application. By enticing a target to view a malicious site, an attacker can exploit these vulnerabilities in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: Libmodplug, a library used by some popular open-source media players, is susceptible to a stack-buffer-overflow vulnerability. Libmodplug is used to play module music files. Module files contain music samples and patterns in which those samples should be replayed. They are similar to MIDI files but are guaranteed to sound the same on all platforms. By enticing a target to open a malicious module music file with a vulnerable application, an attacker can exploit this vulnerability in order to execute arbitrary code on the target's machine. A simple public proof of concept is available for this vulnerability.
Status: vendor not confirmed, updates not available
Part II -- Comprehensive List of Newly Discovered Vulnerabilities from Qualys (www.qualys.com) 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 11219 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
