Part I for this issue has been compiled by Rohan Kotian 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: A remote code execution vulnerability has been identified in Apple Mac OS X. The issue is caused by an indexing error in the Apple Type Services while processing embedded fonts. The specific flaw is in the "TType1ParsingContext::SpecialEncoding()" routine which is defined in " libFontParser.dylib". A document containing a malicious embedded font can be used to trigger this vulnerability. Some technical details for this vulnerability are publicly available.
Status: Vendor confirmed, updates available.
Description: HP Operations Manager is a consolidated performance management console, used to reduce IT management costs. A buffer overflow vulnerability has been identified in the SourceView ActiveX control, which is a component of HP Operations Manager. The issue is caused by a boundary error in "srcvw32.dll" or "srcvw4.dll" module and an attacker can trigger this vulnerability by passing an overly long argument to the "LoadFile()" method. Successful exploitation might allow an attacker to execute arbitrary code in the context of the affected application. Full technical details about the vulnerability are publicly available.
Status: Vendor confirmed, updates available. Users can mitigate the impact of this vulnerability by disabling the vulnerable control via Microsoft's "kill bit" mechanism using CLSID "366C9C52-C402-416B-862D-1464F629CA59". Note that this may impact normal application functionality
Description: Cisco Secure Desktop is an application that facilitates secure VPN connections. A vulnerability has been identified in Cisco Secure Desktop that might cause an unsuspecting users to download executables on to their systems. The issue is caused by an error in the Cisco signed ActiveX control, Secure Desktop Web Install ActiveX control. This control fails to verify the signature of the downloaded executable file that is used by the Cisco Secure Desktop installation process. An attacker controlled malicious web page that invokes this ActiveX control can be used to trigger this vulnerability. Successful exploitation might allow an attacker to execute arbitrary code with the privileges of the affected user. Some technical details for the vulnerability are publicly available.
Status: Vendor confirmed, updates available.
Description: Helix Server and Helix Mobile Server is a popular streaming media server from RealNetworks. Multiple vulnerabilities have been reported in Helix Server and Helix Mobile Server. The first issue is caused by a heap overflow error in the NTLM authentication in Helix Server in the way it processes invalid base64. The second issue is caused by a stack-based overflow error in the AgentX++. The third issue is caused by an integer overflow error in the AgentX++. Successful exploitation of these vulnerabilities might allow an attacker to execute arbitrary code. Some technical details for some of the vulnerabilities are publicly available.
Status: Vendor confirmed, updates available.
Description: Google Chrome, a web browser from Google, is the fourth most popular browser with 4.63% usage share among all the web browsers. Multiple vulnerabilities have been reported in Google Chrome in the way it handles various inputs. The vulnerabilities reported include cross-site request forgery, cross-site scripting, memory corruption errors, cross-domain access, and privilege escalation. Full technical details for these vulnerabilities are publicly available via source code analysis.
Status: Vendor confirmed, updates available.
Part II -- Comprehensive List of Newly Discovered Vulnerabilities from Qualys (www.qualys.com) Week 17, 2010 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 9136 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
