A look at the Auditor Security Collection
The
Auditor Security Collection team has just put out a new release. The Auditor Security Collection is a Knoppix-based live CD with
a huge selection of security tools that can be used for security audits and penetration testing.
The latest release includes two different ISO images -- one for systems with Intel B/G wireless cards, and one without.
We tried Auditor on a workstation and notebook computer. Auditor detected all of the hardware, even the wireless card in the notebook, flawlessly. Unlike Knoppix, Auditor does not automatically attempt to get an IP address by DHCP on boot -- the user must do this manually.
There are far too many applications included with Auditor to go into each one individually. The CD includes several classes of applications, found on the KDE menu in the "Auditor" menu. The menu classes include "Footprinting," "Scanning," "Analyzer," "Spoofing," "Bruteforce," "Forensics" and "Password cracker." Suffice it to say that Auditor includes a comprehensive list of tools for any user who needs to perform a security audit.
Of course, Auditor could be applied to less-than-honest endeavors as well. Using Auditor, we were able to quickly start up EtherApe to start monitoring network traffic on our LAN, use Dsniff to scan for passwords sent over the network, and run Nessus to scan for vulnerabilities. Given a laptop, wireless card and close proximity to a unprotected (or under-protected) wireless network, and a user could walk away with quite a few passwords and usernames just by casual browsing.
In addition to scanning and penetration testing, Auditor would come in handy for forensics on compromised computers with tools like Wipe, Sleuthkit, recover and testdisk. Auditor also includes a decent selection of normal productivity tools, which will come in handy for admins and security consultants to produce full reports on the same machine they use for scanning and penetration testing. Auditor includes several text editors, image capture tools, and even vnc2swf for users who need to make Flash movies of their tests.
The Remote-Exploit website also has links to Flash movies demonstrating various uses of the Auditor Security Collection, including cracking 128-bit WEP and decrypting SSL traffic using a Man in the Middle attack.
In short, Auditor is a one-stop shop for Linux users who want a full selection of security testing tools. We'd recommend that any system administrator take a look at Auditor, and consider adding it to their security tool chest. If nothing else, it should provide an eye-opener as to what kinds of easy-to-use tools are available to potential attackers.

| Created: | October 29, 2004 |

| Description: |
Several buffer overflows have been discovered in libgd's PNG handling
functions.
If an attacker tricked a user into loading a malicious PNG image, they
could leverage this into executing arbitrary code in the context of
the user opening image. Most importantly, this library is commonly
used in PHP. One possible target would be a PHP driven photo website
that lets users upload images. Therefore this vulnerability might lead
to privilege escalation to a web server's privileges.
Multiple buffer overflows in the gd graphics library (libgd) 2.0.21 and
earlier may allow remote attackers to execute arbitrary code via malformed
image files that trigger the overflows due to improper calls to the
gdMalloc function. |

libnet-ssleay-perl: weakened cryptographic operations
| Package(s): | libnet-ssleay-perl |
CVE #(s): | CAN-2005-0106
|
| Created: | May 3, 2005 |
Updated: | January 27, 2006 |
| Description: |
Javier Fernandez-Sanguino Pena discovered that this library used the
file /tmp/entropy as a fallback entropy source if a proper source was
not set in the environment variable EGD_PATH. This can potentially
lead to weakened cryptographic operations if an attacker provides a
/tmp/entropy file with known content. |

libTIFF: buffer overflow
| Package(s): | libtiff |
CVE #(s): | CAN-2005-1544
|
| Created: | May 10, 2005 |
Updated: | February 17, 2006 |
| Description: |
Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
stack based buffer overflow in the libTIFF library when reading a TIFF
image with a malformed BitsPerSample tag. Successful exploitation would
require the victim to open a specially crafted TIFF image, resulting in the
execution of arbitrary code. |

lvm10: creates insecure temporary directory
| Package(s): | lvm10 |
CVE #(s): | CAN-2004-0972
|
| Created: | November 1, 2004 |
Updated: | July 25, 2005 |
| Description: |
Trustix Secure Linux discovered a vulnerability in a supplemental script of
the lvm10 package. The program "lvmcreate_initrd" created a temporary
directory in an insecure way, which could allow a symlink attack to create
or overwrite arbitrary files with the privileges of the user invoking the
program. |
