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: Mozilla has released patches for multiple vulnerabilities affecting its Firefox browser. The problems include memory safety bugs, a problem that allows unsigned JAR files to call signed ones, thus inheriting their identity, buffer overflows in WebGL, and a dangling pointer vulnerability in its code for handling SVG. By enticing a target to view a malicious page, an attacker can exploit some of these vulnerabilities in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: Check Point has released a patch for vulnerabilities affecting its SSL VPN on-demand applications. These SSL VPN applications, which include SSL Network Extender, SecureWorkSpace, and Endpoint Security On-Demand, are driven on the client side by an ActiveX control or Java applet. Both of these contain public methods that can be used to trivially write arbitrary files to the disk. Another public method executes a file in a particular location. Together, these methods can be used to trivially execute arbitrary code on the client's machine. An attacker must entice a target to view a malicious site in order to exploit this vulnerability.
Status: vendor confirmed, updates available
Description: RealNetworks has released a patch for multiple vulnerabilities affecting its RealPlayer multimedia player. The problems include buffer overflow and memory corruption vulnerabilities as well as a problem handling HTML files, which are allowed to run scripts without prompting the user for verification. By enticing a target to view a malicious page, an attacker can exploit these vulnerabilities in order to execute arbitrary code with the permissions of the currently logged in user.
Status: vendor confirmed, updates available
Description: MPlayerhq has released a patch for MPlayer to address a buffer overflow vulnerability in its sub_read_line_sami() function. The function is used for handling SAMI (Synchronized Accessible Media Interchange) files, which contain captions for video and sound files. By enticing a target to view open a malicious SAMI file with MPlayer or SMPlayer, an attacker can exploit this vulnerability in order to execute arbitrary code on the target's machine.
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 12068 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
