@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).

Almost unheard of ten years ago, electronic discovery is today chewing up IT resources - equipment, services and staff time. Recognizing that many electronic records such as e-mail, spreadsheets and text messages might some day be demanded in a lawsuit or freedom-of-information request, what policy should your enterprise adopt for retaining and destroying electronic records? Find out at the: SANS WhatWorks: Legal Issues and PCI Compliance in Information Security Summit 2010 http://www.sans.org/info/63168

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/cva/#process
Description: Adobe Acrobat and Reader are susceptible to an integer overflow error. By enticing the user to download and view a malicious PDF, an attacker can exploit this vulnerability in order to execute arbitrary code. The specific error is due to an error in Reader's code to parse TrueType fonts.
Status: vendor not confirmed, updates not available
Description: Apple iPhone's iOS is susceptible to vulnerabilities that allow the execution of arbitrary code with escalated privileges. The first vulnerability is due to an error in the way iOS loads certain fonts within PDF files. The second vulnerability, which exists in the kernel, allows for privilege escalation. By enticing the target to download and view the file, an attacker can exploit these vulnerabilities in order to inject code be run with privileges sufficient to jail break the iPhone; in fact, these particular vulnerabilities have been already used for that purpose. Apple is aware of the issue and reportedly prepared to release a patch for the vulnerability, which could easily be used maliciously.
Status: vendor confirmed, updates not available
Description: Apple WebKit is a browser engine used in popular web browsers, including Apple Safari and Google Chrome. Apple has recently patched two code-execution vulnerabilies in WebKit. The first vulnerability is related to WebKit's handling of the CSS first-letter style. Under certain circumstances, the application of this style can lead to memory corruption and code execution. The second vulnerability is related to WebKit's handling of a particular SVG tag, which, under certain circumstances, can lead to memory corruption and code execution. Other memory corruption vulnerabilities exist due to WebKit's handling element focus, inline elements, dynamic modifications to text nodes, floating elements in SVG documents, 'use' and 'font-face' elements in SVG documents, JavaScript string objects, just-in-time compiled JavaScript stubs, JavaScript arrays, and regular expressions.
Status: vendor confirmed, updates available
Comprehensive List of Newly Discovered Vulnerabilitis from Qualys (www.qualys.com <http://www.qualys.com> <http://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 9795 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
