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: Google has released patches addressing multiple vulnerabilities in its Chrome web browser. The vulnerabilities include a double free in its theora decoder, a memory corruption in VP8 decoding, buffer overflows in the Vorbis decoder and shader variable mappings, and a use-after-free in editing. The technical details surrounding these vulnerabilities are not publicly available, but it is likely that an attacker could exploit these vulnerabilities in order to execute arbitrary code on a target's machine by enticing the target to view a malicious page.
Status: vendor confirmed, updates available
Description: Apple has released a patch addressing multiple security vulnerabilities in its iOS mobile operating system. The vulnerabilities include memory corruptions in the FreeType font library. By enticing a target to view maliciously crafted files, an attacker could exploit this vulnerability in order to execute arbitrary code on the target's machine.
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 12689 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely. ______________________________________________________________________
