Adobe PDF Zero Day Warnings : Experts agree

All the Security experts online are talking about The 2 Zero Day Adobe Vulnerabilities:

[ad#cricket-right-ez]As you can see this seems to be one of those Adobe problems we had in the past with [intlink id=”2963″ type=”post”]Javascript[/intlink].   They seem to be having a major problem with Javascript vulnerability and the old saying is to just to disable Javascript in PDF’S again.   Adobe is calling this a Potential Adobe Reader issue and is suggesting that the users disable Javascript until this is fixed with a security update.

This is mostly affect the corporate world more than the private sector because of the fact corporate world will use PDF by sending them through emails.   I suggest installing another reader and these are all free.

Be advised the vulnerabilities affects Linux, Windows, and Macintosh systems.  This will most likely mean that even Macintoshes could be used to [intlink id=”2173″ type=”post”]create even more botnets[/intlink] and will need to disable there Javascript until this issue is fixed or maybe they would like to find another reader themselves.  This also goes for Linux users but I have not heard of anything in the wild yet.

Don’t forget to install some [intlink id=”2205″ type=”page”]free Anti-virus and Free Firewalls[/intlink] to help protect your system from becoming a botnet.

Microsoft sends out KB955430 to get ready for SP2

kb955430

This looks like it is to help with some problems with other issues of updates that they have been having.  I am unsure of why they are wanting to install this update but it doesn’t look to be harmful.  I am betting this is to fix a flaw that has been exploited by the warez community to make them either pay for there copy or go with another OS.   For the one fact that this “will enable future updates” and “This update may be required before selected future updates can be installed“.

[ad#cricket-right-ez]I went to  KB9555430 support page:

Updates to the Windows Vista and Windows Server 2008 installation software are included in this update. The installation software is the component that handles the installation and the removal of software updates, language packs, optional Windows features, and service packs. This update is necessary to successfully install and to remove Windows Vista SP2 and Windows Server 2008 SP2 on all versions of Windows Vista and Windows Server 2008. This update is not necessary to successfully install the service pack if you install the full file version of the service pack. The full file version of the service pack includes this update.

This is probably to get ready for the Service Pack that they are going to release soon for Vista. So I am guessing this will be required when the Service Pack comes out.

Patch Tuesday List for April 14, 2009

So Microsoft has released the patches for April and here they are:

  1. Vulnerabilities in Windows Could Allow Elevation of Privilege (KB959454) — This security update resolves four publicly disclosed vulnerabilities in Microsoft Windows. The vulnerabilities could allow elevation of privilege if an attacker is allowed to log on to the system and then run a specially crafted application. The attacker must be able to run code on the local machine in order to exploit this vulnerability. An attacker who successfully exploited any of these vulnerabilities could take complete control over the affected system.
  2. Vulnerabilities in Windows HTTP Services Could Allow Remote Code Execution (KB960803) — This security update resolves one publicly disclosed vulnerability and two privately reported vulnerabilities in Microsoft Windows HTTP Services (WinHTTP). The most severe vulnerability could allow remote code execution. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  3. [ad#cricket-right-ez]Cumulative Security Update for Internet Explorer (KB963027) — This security update resolves four privately reported vulnerabilities and two publicly disclosed vulnerabilities in Internet Explorer. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer or if a user connects to an attacker’s server by way of the HTTP protocol. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  4. Blended Threat Vulnerability in SearchPath Could Allow Elevation of Privilege (KB959426) — This security update resolves a publicly disclosed vulnerability in the Windows SearchPath function that could allow elevation of privilege if a user downloaded a specially crafted file to a specific location, then opened an application that could load the file under certain circumstances.
  5. Vulnerabilities in Microsoft ISA Server and Forefront Threat Management Gateway (Medium Business Edition) Could Cause Denial of Service (KB961759) — This security update resolves a privately reported vulnerability and a publicly disclosed vulnerability in Microsoft Internet Security and Acceleration (ISA) Server and Microsoft Forefront Threat Management Gateway (TMG), Medium Business Edition (MBE). These vulnerabilities could allow denial of service if an attacker sends specially crafted network packages to the affected system, or information disclosure or spoofing if a user clicks on a malicious URL or visits a Web site that contains content controlled by the attacker.
  6. Vulnerability in Microsoft DirectShow Could Allow Remote Code Execution (KB961373) –This security update resolves a privately reported vulnerability in Microsoft DirectX. The vulnerability could allow remote code execution if user opened a specially crafted MJPEG file. An attacker who successfully exploited this vulnerability could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
  7. Vulnerabilities in WordPad and Office Text Converters Could Allow Remote Code Execution (KB960477) — This security update resolves two publicly disclosed vulnerabilities and two privately reported vulnerabilities in Microsoft WordPad and Microsoft Office text converters. The vulnerabilities could allow remote code execution if a specially crafted file is opened in WordPad or Microsoft Office Word. Do not open Microsoft Office, RTF, Write, or WordPerfect files from untrusted sources using affected versions of WordPad or Microsoft Office Word.
  8. Vulnerabilities in Microsoft Office Excel Could Cause Remote Code Execution (968557) — This security update resolves a privately reported and a publicly disclosed vulnerability. The vulnerabilities could allow remote code execution if the user opens a specially crafted Excel file. An attacker who successfully exploited these vulnerabilities could take complete control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

As you can see there are Eight updates and it seems Microsoft isn’t pushing anything else with this update.   We also have the Malicious Software Removal tool for this month as well as the Junk Filters.   If you want to keep your system secure I’d suggest getting a [intlink id=”2205″ type=”page”]Free Firewall and Free Anti-virus[/intlink].   If you have a lot of systems to update, I’d also suggest what I have been calling[intlink id=”2883″ type=”post”] Clone of Autopatcher[/intlink].  This will download them onto a ISO for you to burn and use around all the systems that are offline.

Microsoft released April Patch list for Patch Tuesday

aprilpatchtue

To see what systems are affected please see the bulletin for further details.   Some of the updates have to do with IE 6 and IE 7, maybe it is time to update to IE 8.  It looks like if you update to IE 8 you will not have to worry about the Remote Code Execution.  There also seems to be a remote code execution for DirectX 9.0A, B, and C.  This however doesn’t affect DirectX 10 and if you have a Vista machine please consider updating to DirectX 10.

[ad#cricket-right-ez]

The other one is a MSDTC program that has a vulnerability of Elevation of Privileges that needs to be fixed.  There will of course be more than this for April but these are the ones that Microsoft has determined to be release for Tuesday.  There are going to be at least 8 Different patches for Windows XP, and some For Vista.  Some will be only for XP and others will be for XP and Vista.

Then Microsoft Internet Security andAcceleration server will have an update to prevent a Denial of Service attack.  This will be needed to patch on the server side as soon as possible.  Then there is the Excel Remote Code execution that needs to be fixed.  It looks like CVE-2009-0238 is the one that this is being patched for but this is only a guess.

Now is the best time to get [intlink id=”2883″ type=”post”]Autopatcher[/intlink] ready for this update because this will be quite a big update.  You should also update your [intlink id=”2205″ type=”page”]anti-virus software and Firewall[/intlink].
