Cisco and Other Vendors Vulnerable to Denial of Service (DoS) flaws

Posted Thu, 10/09/2009 - 23:00 by Admin

The Finnish Computer Emergency Response Team (CERT-FI) has released an alert which lists a number of vendors that have reported vulnerability to a new Denial of Service (DoS) vulnerability.  A DoS attack on the flaw can cause network devices to crash or lockup generating service outages for your network.

The vulnerability was discovered by researchers utilising a testing tool known as Sockstress, but can be replicated by flooding a device with specially crafted data packets (TCP packets in particular).

Below is a list of the affected vendors and links to their alerts:

[AzTechNotes] Web Hosting FTP virus warning - GUMBLAR

Posted Fri, 31/07/2009 - 22:52 by Admin
Attn: Aztech Hosting Clients and AztechNotes Subscribers,
 
Firstly, apologies if you receive this email twice because you are on both lists but I thought it worth making sure everyone receives this virus warning.
 
It has been quite some time since we have seen a security alert that is worth passing on, however there is a growing concern in the security fields regarding a virus commonly known as "Gumblar".  The virus is named after the original Chinese domain name (gumblar .cn) that hosted the malicous code, but this site has since been closed and an alternative domain has been established.

Microsoft Patch for high cpu (100%) usage by svchost

Posted Sun, 18/01/2009 - 20:38 by Admin

Micrsoft patch released for the 100% CPU utilisation by svchost problem during software update checks.

If you are one of the millions of customers that have experienced the problem of high cpu use by svchost when the system checks for updates, then relief is at hand.  The most common symptom is extremely poor performance after initial boot and a check of processes in Task Manager shows "svchost.exe" using 100% cpu.

TCPView from Sysinternals

Posted Tue, 30/12/2008 - 12:30 by Admin

 

A great little utility I use all the time is TCPView from Sysinternal (MS Technet). 

 

This little program shows you which application is using which TCP or UDP ports on your workstation.  It is fantastic for identifying what is generating outgoing connections from a PC.  Particularly with todays prevelant amount of Malware / Spyware out there, it is great to see what is happening on your PC in the background (usually without your knowledge).

[AzTechNotes] Phishing Season is open and Flash Player Vulnerability

Posted Thu, 12/06/2008 - 00:28 by Admin

Hi Everyone,

 

It has been a while since my last TechNote, which might really mean good
news.  If I haven't had to send out any security alerts, then that is a good
thing. Eye-wink

The only really pertinent alert in the last month is a security
vulnerability of "Adobe Flash Player" which is exploited when you visit a
malicious Flash (.swf) file.  There is no patch for the player, so best
defence is really to avoid any suspect sites (which is always good advice).
