The Apple Mac has multiple critical remotely-exploitable vulnerabilities reported this week. Alan
@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).
************** Sponsored By SANS COMPLIANCE WORKSHOP ******************
Many INFOSEC professionals know that "being compliant" does not guarantee a secure infrastructure. SANS invites you to attend this archived webcast which has helped hundreds assess the future trends of compliance and vulnerability management. The "must-know" topics of network vs. vulnerability scanning, compliance mandates (PCI/DDS, ISO 27000/SOX, HIPAA), and the recent evolution of network assessment and what is needed to help mitigate the latest threats are discussed. Featuring David Hoelzer and sponsored by Qualys.

Part I for this issue has been compiled by Rohan Kotian 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 Mac OS X contains multiple vulnerabilities in several of its components. Improper handling of user and network requests, and several file, document, and media formats, can cause memory corruption and/or buffer overflow leading to arbitrary remote code execution with the privileges of the vulnerable process. Other logical flaws can lead to arbitrary information disclosure, denial of service, file overwrites, null pointer dereference, escalation of privileges. Several of these vulnerabilities stem from flaws in included third-party applications and components.
Status: Vendor confirmed, updates available.
Description: FreeBSD telnet daemon, telnetd, has a remote code execution vulnerability. Due to insufficient sanitization of user supplied inputs, potentially harmful environment variables can be set. This is primarily caused due to some recent changes in FreeBSD's environment handling code. Successful exploitation of this vulnerability may allow an attacker to execute arbitrary code with the privileges of the user running the vulnerable telnet daemon service. Note that telnetd is disabled by default. Some technical details are publicly available for this vulnerability
Status: Vendor confirmed, updates available.
Description: Microsoft XML Core Services allows users who use JScript, VBScript and Microsoft Visual Studio 2005 to build XML based applications and is used in Microsoft Office, Internet Explorer 6 and 7, and other products. Microsoft XML Core Services is prone to information disclosure due to improper handling of HTTPOnly cookie flag by XMLHttpRequest. This can be leveraged by the attackers to sensitive information from cookies, which can be used for other attacks. Some technical details are publicly available for this vulnerability.
Status: Vendor has not confirmed, no updates available.
Description: Symantec Veritas NetBackup is a backup and recovery suite that provides cross-platform backup functionality. Symantec Veritas Netbackup has a remote escalation of privilege vulnerability due to inadequate sanitization of server-supplied data during initial communication setup. This could be leveraged by the remote authorized attackers who have access to the target network to execute arbitrary code with elevated privileges. Some technical details are publicly available for this vulnerability.
Status: Vendor confirmed, updates available.
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 5549 unique vulnerabilities. For this special SANS community listing, Qualys also includes vulnerabilities that cannot be scanned remotely.
