1) Special Webcast February 23: How to Avoid Being Compromised! Featuring Dr. Eric Cole, Part 1 http://www.sans.org/info/70078 *************************************************************************
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: Microsoft's Active Directory implements, among other things, the CIFS (Common Internet File System) BROWSER protocol, which facilitates the exchange of information about resources available on a network using the CIFS protocol. Active Directory is susceptible to an integer overflow vulnerability that causes a large amount of memory to be copied into a fixed-length buffer. Because the size of the data is guaranteed to be very large, an exploit attempt is extremely likely to trigger a bug check and terminate the program. For this reason, the Microsoft Security Response Center has reported that reliable remode code execution using this vulnerability is unlikely. The most likely result of an attempted exploit would be a denial-of-service (DOS) vulnerability.
Status: vendor confirmed, updates available
Description: Oracle has released patches for multiple vulnerabilities affecting its Java virtual machine (JVM). Many of the vulnerabilities allow for remote code execution, and all require an attacker to entice a target to view a malicious page. The vulnerabilities include, for example, a vulnerability related to the JVM's handling of untrusted code, which should normally be sandboxed. Because part of the file is parsed incorrectly by the JVM, an attacker can exploit this vulnerability in order to execute arbitrary code with SYSTEM-level permissions on a target's machine. Note that this vulnerability, in particular, can be used to run machine- and operating-system-independent exploit code.
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 10919 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
