Time to update Adobe Flash Player 10.0.22.87

Paul

Adobe has issued a patch for some of the exploits in the wild. This should be installed on any system that isn’t up to the date with Adobe’s player. If you want to check your systems version you can go here and it will tell you what your version is and what the current version is.

If it doesn’t look like this:

adobe1002287

[ad#ad2-right]Then your on the wrong website.   According to Adobe this fixes CVE-2009-0519, CVE-2009-0520, CVE-2009-0522, CVE-2009-0114, CVE-2009-0521.

This update resolves a buffer overflow issue that could potentially allow an attacker to execute arbitrary code. (CVE-2009-0520)

This update resolves an input validation issue that leads to a Denial of Service (DoS); arbitrary code execution has not been demonstrated, but may be possible. (CVE-2009-0519)

An update to the Flash Player settings manager display page on Adobe.com has been deployed to avoid a potential Clickjacking issue variant for Flash Player. The Settings Manager is a special control panel that runs on your local computer but is displayed within and accessed from the Adobe website. (CVE-2009-0114)

This update resolves a Windows-only issue with mouse pointer display that could potentially contribute to a Clickjacking attack. (CVE-2009-0522)

This update prevents a potential Linux-only information disclosure issue in the Flash Player binary that could lead to privilege escalation. (CVE-2009-0521)

Although this is due to the problem with the exploits in the Windows environment, this however won’t stop virus writers from using this exploit for the Macintosh and Linux Distro’s.  This should be updated on there system also.

MS09-004: Vulnerabilities in Microsoft SQL Server could allow remote code execution
(KB959420) (MS09-004)
(CVE-2008-5416)(Exploit code publicly available since December 2008)

This security update resolves a privately reported vulnerability in Microsoft SQL Server. The vulnerability could allow remote code execution if untrusted users access an affected system or if a SQL injection attack occurs to an affected system. Systems with SQL Server 7.0 Service Pack 4, SQL Server 2005 Service Pack 3, and SQL Server 2008 are not affected by this issue.

MS09-003: Vulnerability in Microsoft Exchange could allow remote code execution
(KB959239)(MS09-003)

(CVE-2009-0098 CVE-2009-0099)

This security update resolves two privately reported vulnerabilities in Microsoft Exchange Server. The first vulnerability could allow remote code execution if a specially crafted TNEF message is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could take complete control of the affected system with Exchange Server service account privileges. The second vulnerability could allow denial of service if a specially crafted MAPI command is sent to a Microsoft Exchange Server. An attacker who successfully exploited this vulnerability could cause the Microsoft Exchange System Attendant service and other services that use the EMSMDB32 provider to stop responding.

Each One of these Updates is either important or recommended.  As you can see on all of them it is time to load up Clone of Autopatcher and start downloading these patches.  If you start now you should be able to keep the bad guys away this weekend.  I just loaded it up and it downloaded all the new patches rather quickly.

Now on to the good stuff, As you can see each of these are important to patch your system and each of these patches need to be installed before someone makes a worm or virus to compromise systems.  I can just see people sending out fake emails that would compromise the Media Center trying to install some  Malware.  I can also see people trying to use the IE Vulnerability also, and the Active X.  These should be taken serious and installed before the week is over.  Some other things to consider is having a good Anti-virus and Firewall setup to prevent infection in the first place.  It’s up to us IT guys to keep the employees from doing something they shouldn’t.  Only you can prevent a Virus infection. (I’ll update when more information is available for a week)

Admins are shaking in there boots due to the Ms 09-001 Patch

Paul

I have to talk about this because this is a big deal.   According to Techworld and I’ll quote:

“This one scares me – a lot,” says Eric Schultze, CTO of Shavlik Technologies. “It is a lot like Blaster and Sasser. It is the same exploit vector. If I am an attacker and I can touch NetBios then I can execute code with no credentials.”

[via Techworld]

[ad]Now This is due to the fact of what is happening with an update that came a few months ago the MS 08 – 067 that still people haven’t patched their systems.  According to F-secure the Downadup/Conflicker has grown overnight by a million computers being infected.

Now why are they scared of the recent patch (MS 09-001), because of so many vectors of infection, you don’t need any credentials.  The virus  does not  need to know any passwords or user names to gain access.  Just like the Downadup variant that is hitting the internet right now, this virus tries to access accounts by guessing weak passwords or even putting itself on flash drives or other mobile media to get other systems infected.

So why are admins scared over this new patch?

Most  companies don’t patch there system as quickly as Microsoft would like them to.   You see most companies have quite a few computers depending on the size of the company it could be quite a lot.  So many in fact that it would have several IT personal just to keep the system going.
[ad]

So why don’t they just put the new patches on the systems?

Depending on the size of the company and what they do has a lot to do with them updating there systems.  Some use really special programs or have a network going that is vital.  Even the smallest update to the system could bring the network or the program down.  Most companies liketo test it out on test machine for a while to make sure that the patch doesn’t  prevent the business from doing business.   Here are a few articles that prove why companies do not want to just install patches automatically:

Some companies are using older systems like Windows ME or some older Windows Operating systesm.   Although there isn’t anything we can do about those because Microsoft has stopped supporting them with updates and all.  I know we are all thinking thesame question?

Is there a way to fix the problem with Windows Updates?

I personally don’t have an answer but I am sure hackers will find ways to exploit codes so they can get on your system so way.  I’ve recently read a story about Adware Author and now I understand even more about why people do all of this.

This is one of the questions every admin has to ask themselves?  How do we update all of the systems we are responsible for?  There are no easy answers to this.

Microsoft issues 1 Major update 1-13-09

Paul

Well it has been release Microsoft issued an update to the system:

[ad#ad2-right]

Vulnerabilities in SMB Could Allow Remote Code Execution

Microsoft Security Bulletin MS09-001 – Critical (KB958687)

This security update resolves several privately reported vulnerabilities in Microsoft Server Message Block (SMB) Protocol. The vulnerabilities could allow remote code execution on affected systems. An attacker who successfully exploited these vulnerabilities could install programs; view, change, or delete data; or create new accounts with full user rights. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.

This is one of those updates you really need to install as soon as you can.   You should also get a free firewall or buy one.  I looks to be a vulnerability in the ports and if you’d have a firewall besides windows you should be safe but that is besides the point.   If you are security congenious then you should install this update ASAP.  If your worried this will effect you system then you will need to backup your system before you do this update.  If you feel you’ve might of been infected with this Vulnerability you could always go get a free antivirus program and scan your system.  This is the sure way of fighting a Virus and making sure your safe, although people argue that Paid virus programs are quicker to be updated with virus databases, it’s all in the matter of preferences.

BREAKING NEWS : Microsoft issues 961509

Paul

Microsoft as issued an new security advisory about the possible way someone might be able to take your sensitive information using an invalid digital signature:
[ad#ad2-right-1]

Microsoft is aware that research was published at a security conference proving a successful attack against X.509 digital certificates signed using the MD5 hashing algorithm. This attack method could allow an attacker to generate additional digital certificates with different content that have the same digital signature as an original certificate. The MD5 algorithm had previously shown a vulnerability, but a practical attack had not yet been demonstrated.

[via Windows Technet]

Although Microsoft has stated in the advisory most companies are using the SHA-1 algorithm.  Some are still using the MD5 and should stop using it immediately.   Microsoft says there is none in the wild but you can be bet on it someone will do it sooner or later.  Certificate Authorities should stop using MD5 and go to a much stronger better Algorithm. This is what Microsoft is saying and they aren’t providing much information for the end-user on how to prevent from using MD5 certificates on your system. You can remove the MD5 certificate manually if you are a system administor and want to protect the computers at the office.  Please don’t do this unless you know what your doing, you could very well break your system if you did something like this.
