Part I for this issue has been compiled by Josh Bronson 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 design error exists in Windows code used to parse LNK files. Windows LNK files contain information related to a Shortcut: the target type, location, and filename. An attacker can use this vulnerability to execute arbitrary code with the permissions of the currently logged-in user. The user is only required to open the folder containing the malicious LNK file. This vulnerability is being actively exploited in the wild. One attack vector currently being used is to load the malicious LNK file onto a USB disk. However, it is also possible for the vulnerability to be exploited via network drives.
Status: vendor confirmed, updates not available
Description: Mozilla has recently patched several vulnerabilities, some of which may allow attackers to execute arbitrary code on a client's machine. The specific vulnerabilities include several memory safety bugs in the browser engine, some of which may be exploitable for code execution; a problem running content scripts allows an attacker to execute arbitrary Javascript code with chrome privileges; an integer overflow vulnerability in the handling of CSS scripts; an integer overflow in the handling of the XUL <tree> element; a buffer overflow in the graphics handling code; a problem in Firefox's handling of recursive attribute nodes; a problem with Firefox's method for parsing child elements of a particular tag; and a memory corruption vulnerability in Firefox's NodeIterator interface.
Status: vendor confirmed, updates available
Description: Apple has patched a buffer overflow vulnerability in Apple iTunes' handling of "itpc:" URIS. By enticing the user to follow a malicious link, an attacker could previously exploit this vulnerability in order to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
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 9752 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
