INTRODUCING THE WORLD'S ONLY FIPS 140-2 LEVEL 3 VALIDATED USB FLASH DRIVE

Designed to meet the needs of military, government and demanding enterprise users, the IronKey? S200 series USB flash drives have passed the stringent Security Level 3 tests for the FIPS 140-2 standard. A rugged, tamper-resistant and tamper-evident enclosure protects the critical components, while strong AES 256-bit hardware encryption and active malware defenses safeguard even the most sensitive data. Enterprise-class central management capabilities also make it easy to enforce security policies on fleets of drives and even remotely destroy drives in the field.

---------------------
1.The Scale of Security
By Adam O'Donnell
Human beings do not naturally understand scale. While we speak of financial transactions in the hundreds of billions of dollars as being something as routine as brushing our teeth, we question the value of programs that cost in the single-digit millions and quibble with friends over dollars. Similarly, there are many problems in our industry that, when explained to an outsider, sound like they should have been solved decades ago. It is only when we relate the number of systems that need to be considered in the repair that we truly communicate the difficulty of the problem.

2. Hacker-Tool Law Still Does Little
By Mark Rasch
On August 10, 2007, a new section of the German Penal code went into effect. The statute, intended to implement certain provisions of the Council of Europe Treaty on Cybercrime, could be interpreted to make the creation or distribution of computer security software a criminal offense.

II. LINUX VULNERABILITY SUMMARY
------------------------------------
1. Linux Kernel 'PER_CLEAR_ON_SETID' Incomplete Personality List Access Validation Weakness
BugTraq ID: 35647
Remote: No
Date Published: 2009-07-13
Relevant URL: http://www.securityfocus.com/bid/35647
Summary:
The Linux Kernel is prone to an unauthorized-access weakness because of an error in the definition of the 'PER_CLEAR_ON_SETID' personalities mask, which is defined in the 'include/linux/personality.h' source file.

An attacker can exploit this issue to perform unsafe operations on a vulnerable computer, which may aid in further attacks.

2. LibTIFF Multiple Remote Integer Overflow Vulnerabilities
BugTraq ID: 35652
Remote: Yes
Date Published: 2009-07-13
Relevant URL: http://www.securityfocus.com/bid/35652
Summary:
LibTIFF is prone to multiple remote integer-overflow vulnerabilities because it fails to perform adequate boundary checks on user-supplied data.

An attacker can exploit these issues to execute arbitrary malicious code in the context of a user running an application that uses the affected library. Failed exploit attempts will likely crash the application.

LibTIFF 3.8.2, 3.9, and 4.0 are vulnerable; other versions may also be affected.

3. ISC DHCP 'dhclient' 'script_write_params()' Stack Buffer Overflow Vulnerability
BugTraq ID: 35668
Remote: Yes
Date Published: 2009-07-14
Relevant URL: http://www.securityfocus.com/bid/35668
Summary:
The ISC DHCP client 'dhclient' is prone to a remote stack-based buffer-overflow vulnerability because it fails to properly bounds-check user-supplied input before copying it into a fixed-length buffer.

Successfully exploiting this issue allows a remote attacker to execute arbitrary code with superuser privileges, resulting in a complete compromise of the affected computer.

4. ISC DHCP Server Host Definition Remote Denial Of Service Vulnerability
BugTraq ID: 35669
Remote: Yes
Date Published: 2009-07-14
Relevant URL: http://www.securityfocus.com/bid/35669
Summary:
ISC DHCP Server is prone to a remote denial-of-service vulnerability because it fails to adequately handle specially crafted DHCP requests.

Attackers can exploit this issue to cause the server to terminate, thus denying service to legitimate users.

5. ISC DHCP 'dhcpd -t' Command Insecure Temporary File Creation Vulnerability
BugTraq ID: 35670
Remote: No
Date Published: 2009-07-14
Relevant URL: http://www.securityfocus.com/bid/35670

Exploiting this issue could allow attackers to perform actions with superuser privileges, resulting in a complete compromise of affected computers.

8. Linux Kernel 'tun_chr_pool()' NULL Pointer Dereference Vulnerability
BugTraq ID: 35724
Remote: No
Date Published: 2009-07-17
Relevant URL: http://www.securityfocus.com/bid/35724
Summary:
The Linux kernel is prone to a local NULL-pointer dereference vulnerability.

A local attacker can exploit this issue to execute arbitrary code with superuser privileges or crash an affected kernel, denying service to legitimate users.

This issue was introduced in Linux kernel 2.6.30.

9. Sun Solaris XScreenSaver Local Information Disclosure Vulnerability
BugTraq ID: 35733
Remote: No
Date Published: 2009-07-17
Relevant URL: http://www.securityfocus.com/bid/35733
Summary:
Solaris XScreenSaver is prone to a local information-disclosure vulnerability.

Remote: Yes
Date Published: 2009-07-21
Relevant URL: http://www.securityfocus.com/bid/35755
Summary:
WordPress is prone to a cross-site scripting vulnerability because the application fails to properly sanitize user-supplied input.

An attacker may leverage this issue to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may help the attacker steal cookie-based authentication credentials and launch other attacks.

Versions prior to WordPress 2.8.2 are vulnerable.

12. Adobe Acrobat, Reader, and Flash Player Remote Code Execution Vulnerability

Summary:
Adobe Acrobat, Reader, and Flash Player are prone to a remote code-execution vulnerability.

An attacker can exploit this issue by supplying a malicious Flash ('.swf') file or by embedding a malicious Flash application in a PDF file. Successful exploits may allow the attacker to execute arbitrary code in the context of the user running the affected application. Failed attempts will likely result in denial-of-service conditions.

The issue affects the following:

Reader and Acrobat 9.1.2
Flash Player 9 and 10
