@RISK is the SANS community's consensus bulletin summarizing the most important vulnerabilities and exploits identified during the past week and providing guidance on appropriate actions to protect your systems (PART I). It also includes a comprehensive list of all new vulnerabilities discovered in the past week (PART II).
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: Apple has released patches for multiple vulnerabilities in its iOS and Apple Safari products. These vulnerabilities include multiple buffer overflow and memory corruption vulnerabilities that could be used by an attacker to execute arbitrary code. Apple iOS is used in Apple's iPhone and iPod products.
Status: vendor confirmed, updates available
Description: Apple has released a patch for a security vulnerability affecting the ATSServer (Apple Type Solution Server) component of Mac OS X. The Apple Type Solution Server is responsible for managing fonts used by applications. Through multiple vectors, including serving a malicious file on a web server, an attacker can exploit a sign mismatch vulnerability in the code responsible for parsing PDF files. Exploitation can potentially lead to arbitrary code execution.
Status: vendor confirmed, updates available
Description: ProFTPD, a modular open-source FTP server, is susceptible to a remote, pre-authentication vulnerability that could allow remote code execution with root permissions. Due to a patch addressing another vulnerability, this vulnerability is no longer exploitable for root code execution. However, the underlying issue, an unbounded copy operation in sql_prepare_where(), has reportedly not been patched.
Status: vendor confirmed, updates not 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 10565 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
