PART I Critical Vulnerabilities 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: Oracle has released patches for multiple vulnerabilities affecting its products. Oracle Secure Backup, which provides centralized tape backup management for heterogeneous servers, has been patched to address an unspecified remote vulnerability in Oracle Secure Backup that can be exploited over the HTTP protocol. An unauthenticated attacker can exploit this vulnerability in order to completely violate the integrity of a target Windows system. This vulnerability is less severe on Linux, Unix, and other platforms. Oracle has also released a patch for Fusion Middleware, a platform for applications that runs on multiple operating systems. Oracle JRockit, which is Oracle's JVM (Java Virtual Machine) embedded into Fusion Middleware, was susceptible to an unspecified vulnerability. An unauthenticated remote attacker can exploit this vulnerability in order to completely violate the integrity of a target system.
Status: vendor confirmed, updates available
Description: Apple has released patches for multiple vulnerabilities affecting components of its iOS operating system for mobile devices. The issues include two CoreGraphics vulnerabilities that could be triggered when opening a malicious PDF. The first exists because of a buffer overflow in the component of FreeType responsible for handling TrueType fonts. The second involves an unspecified signedness issue. By enticing a target to open a malicious PDF, an attacker can exploit these vulnerabilities in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: Citrix has released patches for Access Gateway, a system that provides remote access to applications via VPN over SSL, addressing a stack buffer overflow vulnerability in the ActiveX component installed on endpoint systems. The vulnerable ActiveX control does not properly handle HTTP header data sent from a Citrix server. By enticing a target to view a malicious site, an attacker can exploit this vulnerability in order to execute arbitrary code on the target's machine in the context of the currently logged-in user.
Status: vendor confirmed, updates 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 11784 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
