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: Adobe has released a patch addressing multiple security vulnerabilities for its Reader, Acrobat, and Flash Player products. All of these products are widely deployed and used to view multimedia on the web. In addition to some unspecified vulnerabilities, many of the vulnerabilities appear to be related to Adobe's code for parsing images and 3d graphics. Because of the nature of these programs, attackers must entice targets to view malicious documents in order to exploit these vulnerabilities to execute arbitrary code on the target's machine.
Status: vendor confirmed, updates available
Description: Microsoft has coordinated the public disclosure of multiple security vulnerabilities in Microsoft Office. It is probable that these have been silently patched by Microsoft, but the author was unable to obtain this information. The vulnerabilities are all due to parsing Microsoft Office files incorrectly; as such, they require the attacker to entice the target to view a malicious file in order to exploit them. In this way, an attacker can execute arbitrary code on the target's machine. The first flaw exists because Excel trusts a user-provided function pointer. The second flaw exists because, in the process of attempting to display an error regarding a malformed Office Art record, Excel accesses a method in the malformed record. The third flaw, a buffer overflow, exists because of an error in the code responsible for copying attacker-controlled data into a fixed-length buffer. The fourth is a use-after-free vulnerability in the code responsible for parsing office drawings. And the last is due to PowerPoint accessing a non-existent method when deleting an object in an Office Art container.
Status: vendor confirmed, updates available
Description: Real Networks has released a patch for Real Player, its cross-platform multimedia player. Real Player uses temporary files to store internal information about media files it is playing. Because these files are saved with predictable file names, an attacker can guess the names and cause Real Player to parse the files and execute attacker-controlled code. An attacker must entice a target to view a malicious file in order to exploit this vulnerability.
Status: vendor confirmed, updates available
Description: Google has released a patch for its web browser, Google Chrome, addressing multiple security vulnerabilities. The flaws include an unspecified race condition in audio handling, an unspecified crash when printing PDFs, and an unspecified use-after-free condition in image loading. The severity of these vulnerabilities has been rated "High" by Google, which, together with the nature of the vulnerabilities, suggests that they may be exploitable for code execution. Based on their description, it is likely that an attacker would have to entice a target to view a malicious page in order to exploit these vulnerabilities for code execution.
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 10911 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
