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: Apple QuickTime is susceptible to a buffer overflow exploit. The specific vulnerability is related to a boundary error in QuickTimeStreaming.qtx. The vendor has not confirmed or patched the vulnerability, which can lead to code execution. In order to exploit this vulnerability, an attacker must entice the user to download and view a malicious file. This can be done, for example, by luring the target to malicious site.
Status: vendor not confirmed, updates not available
Description: Mozilla Firefox is susceptible to an invalid free vulnerability. Firefox's plugin handler contains the error, which could be leveraged by an attacker to execute arbitrary code with the permissions of the currently logged-in user. The specific vulnerability is due to properties in a plugin instance's parameter array being prematurely freed.
Status: vendor confirmed, updates available
Description: Google Chrome is susceptible to two memory corruption vulnerabilities and one unspecified vulnerability dealing with large canvases. Because Google does not immediately release details of the vulnerabilities it patches, it is impossible to know the severity of these bugs. In particular, it has not been disclosed whether these bugs can lead to code execution. But it should be noted that memory corruption vulnerabilities may often allow code execution.
Status: vendor confirmed, updates available
Comprehensive List of Newly Discovered Vulnerabilitis 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 9778 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
