OpenSSL updates for ALL versions

Submitted by eth00 on

The OpenSSL team released an update that affects all versions of OpenSSL to some degree with the primary issue on affecting version 1.0.1+. There are 5 vulnerabilities fixed by the latest patch ranging from MITM attacks to buffer overflows. The MITM bug allows a specially crafted packet to potentially force a weak keyring and allow for decryption of the SSL content. This bug can be exploited with any version of openssl on the client and version 1.0.1+ on the server. Updates have been released for all versions of OpenSSL, including below 1.0.1 to mitigate this issue.

Archipel build error - python-setuptools

Submitted by eth00 on

While trying to do an initial install of Archipel the following error was encountered on a CentOS 6 64bit machine:

ArchipelAgent]# ./buildAgent -d
MESSAGE: Performing the developer installation
Traceback (most recent call last):
File "setup.py", line 18, in

This issue is that python-setuptools was not installed. Installing it should fix the error:

Ossec ar.conf issue

Submitted by eth00 on

While setting up a new ossec cluster I encountered the following error when trying to restart ossec on the client server using /var/ossec/bin/agent_control 001 :

ossec-execd(1103): ERROR: Unable to open file '/var/ossec/etc/shared/ar.conf'.
ossec-execd(1311): ERROR: Invalid command name 'restart-ossec0' provided.

The issue is a problem with ownership on the ar.conf file. By default ossec installs it with root:root permissions but it needs to be root:ossec.

#chown root:ossec /var/ossec/etc/shared/ar.conf

Linksys 0-day Exploit

Submitted by eth00 on

Security researchers at DefenseCode uncovered a 0day exploit within the linksys firmware. They have only tested it on the WRT54GL but believe other models will be vulnerable. At the moment only security researchers appear to have the exploit code. Per defensecode's vulnerability disclosure policy they are going to release the full details of the attack on January 25th.

0-Day in Java 1.7

Submitted by eth00 on

A new exploit in java has been made public, details can be found here: http://malware.dontneedcoffee.com/2013/01/0-day-17u10-spotted-in-while-d...

It appears the exploit has been around for at least some time as two different exploit kits already include it. At the moment the only fix is to disable java. If you need java I would suggest running it on a specific browser used only for that, ideally within a virtual machine.

Qualys SSL checker

Submitted by eth00 on

Encryption is vital to any website that takes information that should not be viewable by others. Ecommerce sites are one of the more obvious places for SSL but login pages should be and many contact forms would ideally be encrypted.

A decent check of your website to make sure that SSL is properly configured can be found here: https://www.ssllabs.com/ssltest/

Libvirtd starting problems

Submitted by eth00 on

The following error was encountered while trying to get libvirtd running:

libvirt version: 0.9.10, package: 21.el6_3.1 (CentOS BuildSystem , 2012-07-03-16:15:49, c6b8.bsys.dev.centos.org)
error : virNetServerMDNSStart:460 : internal error Failed to create mDNS client: Daemon not running

Note that I had to check /var/log/libvirt/libvirt.log as a service libvirtd start looked fine, a restarted was failing on stopping it.

The issue comes from avahi not running. Go ahead and install it and get messagebus running via:

Plesk 0 day exploit

Submitted by eth00 on

If you are running Parallels Plesk control panel (both linux and windows) check out this article: http://krebsonsecurity.com/2012/07/plesk-0day-for-sale-as-thousands-of-s...

Plesk reports that patching can help it but some are reporting that even patched servers may be vulnerable to this exploit. The most common attack seems to be uploading an iframe that can be then used to distribute malware to people surfing the site.

Welcome to the new page!

Submitted by eth00 on

Well its about that time...time for a new page! I have done a complete revamp of the backend and have everything up to the latest and greatest versions. The last few years have gone by in the blink of an eye, now after changing jobs I have a bit more time and plan to use some of that time to rejuvenate the site.

Enjoy your visit! =-)
