Flash under attack, emergency patch issued: Update immediately | ZDNet
Adobe has issued an emergency fix for Flash to prevent two ongoing malware attacks against the world's most popular Web plug-in.US-CERT Current Activity
In an advisory note, Adobe announced the latest release of Flash Player 11.5, which will patch two security zero-day vulnerabilities that are actively being used by hackers and malware writers to spread malware.
Adobe Releases Security Advisory for Adobe Flash Player
Tuesday, December 11, 2012
What a busy Tuesday: Microsoft had a BIG Patch Tuesday compounded by Adobe's Patch Tuesday and Oracle's Patch Tuesday all at once. There are security patches for the Adobe Flash Players and Adobe AIR. Oracle issued a security-enhancing patch for Java JRE 7. There is an update for Java JRE 6, but it does not fix any security issues.
The SANS Diary entry for Microsoft lists many of the items, including an IE patch and a patch for Microsoft Word, as CRITICAL*, so you shouldn't delay patching past Friday if you use IE or Word.
- * Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.

- It’s That Time of Year, For the December 2012 Bulletin Release - MSRC - Site Home - TechNet Blogs
... today we’re releasing seven bulletins, five Critical-class and two Important-class, addressing 12 vulnerabilities in Microsoft Windows, Internet Explorer (IE), Word and Windows Server. For those who need to prioritize deployment, we recommend focusing on the following two critical updates first: ....
- Microsoft fixes critical Windows 8, IE10 flaws for Patch Tuesday | ZDNet
Summary: Put a pot of coffee on, it's Patch Tuesday. Microsoft today released five critical patches that fix vulnerabilities in Windows 8 devices, including Surface tablets, and Internet Explorer 10.
Microsoft has released five critical security updates for Windows 8 and Windows RT in order to protect against a range of vulnerabilities identified in the recently released software.
All in all, there are seven updates for Windows users, with five rated "critical" that could lead to remote code execution, while two are rated "important," which fix flaws that could result in the operating system's security features being bypassed.
- Critical Updates for Flash Player, Microsoft Windows — Krebs on Security
Adobe and Microsoft have each released security updates to fix critical security flaws in their software. Microsoft issued seven update bundles to fix at least 10 vulnerabilities in Windows and other software. Separately, Adobe pushed out a fix for its Flash Player and AIR software that address at least three critical vulnerabilities in these programs.
A majority of the bugs quashed in Microsoft’s patch batch are critical security holes, meaning that malware or miscreants could exploit them to seize control over vulnerable systems with little or no help from users. Among the critical patches is an update for Internet Explorer versions 9 and 10 (Redmond says these flaws are not present in earlier versions of IE).

Articles on Oracle's Java Patches are few as of this writing, all I have managed to find is the download page for Java. There are links to the "Release Notes" pages for Java 6 and 7 on the download page:
- Java SE Downloads
Java SE 7u10
This releases brings in key security features and bug fixes. Oracle strongly recommends that all Java SE 7 users upgrade to this release.
Friday, September 7, 2012
1. Uninstall Java or go back to version 6. If you have Java installed on your computer and don't need it, UNINSTALL IT. There is an unpatched flaw in the all releases of version 7 which can be used in drive-by downloads to infect your computer just by visiting a hacked or malicious website. Check your version number here: Verify Java Version If you must use Java for any reason, I recommend uninstalling version 7 and getting version 6u35, which does not have the same flaws. If you have to have it for some reason, disable it in your browser except when needed. More below, and please feel free to email me (with your browser version) if you need help disabling Java.
2. Update Flash Player (or uninstall it). Flash Player, required for Youtube and other videos, is now at version 11.4.x for Windows (different version numbers for Mac, Linux, and Android) If you have it and are not at the current version, update it ASAP. Check your version number here: Adobe Flash Player.
3. Update your PDF Reader. My current PDF Reader is Sumatra PDF (v2.1.1(, but I also have the latest Foxit Reader (v5.4) installed. Both were updated this summer. If you still have Adobe Reader, you should be at version 9.5.2 or 10.1.4 as earlier versions have known "in the wild" exploits against them.
4. Do Windows Updates. If you do not have Windows Update set to automatic, you need to update Windows. Several critical issues were fixed in the August and September Patch-Tuesday events. See these ISC pages (July and August) for more technical details or these ZDNet pages (July and August) and Krebs on Security pages (July and August) for user-friendly discussions.
5. Update Apple Remote Desktop. Apple Remote Desktop, which many Mac users use to connect to their home or office computer while on the road, would connect insecurely without informing the remote user.

If you run iTunes, you need to update it.
One final story got left out of my last blog post about Microsoft updates. It's the first link below. If you run IE, PATCH NOW!
There are some additional security patches which may be of minor interest. On Monday, May 14, 2012, I posted a notice that Adobe to patch Illustrator, Photoshop, and Flash Pro CS5.x for free, Well, they have finally issued patched the last member of the three, Flash Pro. Google's Chrome browser got patched again, but since it auto-updates you should already be using this version. If you use WinAmp, you should patch to the latest version. Links are below.
- Bad guys using unpatched Internet Explorer flaw to hack Gmail accounts
Last week, Google warned its users that “state-sponsored attacks” were under way aimed at accessing Gmail accounts. Those targeted saw a message at the top of their Gmail inboxes warning that “state-sponsored attackers may be attempting to compromise your account or computer”.
At the time, Google was mum on the specific exploit, but on Wednesday Microsoft provided details in a security advisory, and they’re not pretty. Google also discussed the exploit in its own blog post.
Cyberscum are taking advantage of an unpatched, zero-day flaw in Windows XP or later to run malicious code on the user’s computer. The code is planted when the user visits a poisoned website using any version of Internet Explorer. The exploit also works through Microsoft Office documents.
This is a silent, drive-by download. If you’re attacked, you may not know it . . . unless you get that cryptic message atop your Gmail inbox.
On Tuesday, Microsoft release some security fixes for Windows, but a patch for this flaw was not included. Don’t think your Windows PC is protected if you conscientiously updated this week. However, Microsoft has released a “Fix It For Me” item that will block the exploit. All Windows users should apply this, even if you don’t use IE or Gmail, but keep in mind it does not fix the underlying flaw in Windows. A future patch – possibly one released before the next Patch Tuesday – will be released for a true fix.
- Apple, Oracle Ship Java Security Updates — Krebs on Security
Wednesday, June 13th, 2012
There must have been some rare planetary alignment yesterday, because the oddest thing happened: Apple and Oracle both shipped software updates for the same Java security flaws on the very same day. ... The update Oracle released yesterday, Java 6 Update 33 and Java 7 Update 5, fixes at least 14 security flaws in the oft-attacked software that is installed on more than three billion devices worldwide. Apple’s Java update brings Java on the Mac to 1.6.0_33, and patches 11 of the 14 security vulnerabilities that Oracle fixed in Tuesday’s release. It’s unclear whether those other three flaws simply don’t exist in the Mac version of Java, but we’ll take progress where we can get it.
- ISC Diary | Java 7u5 and 6u33 released
Oracle is releasing Java 7 update 5 and Java 6 update 33 today.
Updated after Oracle released the vulnerability details.
- Release notes for 6u33
- Release notes for 7u5
- Advisory (contains their risk matrix)
- More verbose version of their risk matrix
Unfortunately it's all still made to be useless to determine what the problems are with the software and perform your own risk assessments.
Just note there are CVSS scores of 10 in there, and in the past months we saw what slacking on patching Java can do (Ref: the recent Apple Mac OS X malware), so just patch this on a rather urgent time schedule due to lack of detailed descriptions.
My words above were barely written or I got the notification of Apple that they are releasing Java for OS X 2012-004 and Java for Mac OS X 10.6 Update 9 today as well. This brings them in line with the updates to 1.6.0_33 above as well as implementing the deactivation of the Java browser plugin and Java Web Start if they remain unused for 35 days to Snow Leopard and deactivating the Java browser plugin and Java Web Start if they do not meet the criteria for minimum safe versions (on Both Lion and Snow Leopard.

- Winamp 5.63 fixes four critical security vulnerabilities | ZDNet
By Dancho Danchev | June 27, 2012, 10:30am PDT
Summary: Winamp version 5.63 fixes four critical security vulnerabilities.
As originally reported in Winamp’s release announcement, version 5.63 fixes four critical security vulnerabilities. Successful exploitation of the vulnerabilities allows execution of arbitrary code. For the exploitation to take place, a user running an outdated version of Winamp, would have to open a specially crafted . AVI video file.
More details about the vulnerability can be found in this Secunia advisory.
Windows Updates for June, 2012, included some critical patches, and one that ISC rated PATCH NOW! to fix a soon-to-be-in-the-wild flaw in Microsoft Internet Explorer and Microsoft Office. If you have not patched any of your systems where you use IE or Office, you need to do so ASAP. In addition, Microsoft issued a separate advisory about a "browse-and-get-owned flaw that can be triggered when an Internet Explorer user on any supported version of Windows visits a specially crafted Web page. Microsoft does not have an official patch available yet for this flaw, but it has issued a FixIt tool workaround that effectively disables the vulnerable component"
Not quite one week later ZDnet published an article stating that the IE/Office vulnerability was now available to hackers. Many other security sites are reporting on these issues. Lots of useful links and technical info are below.
If you use IE for your Internet surfing, you should run Windows Update AND run the MS FixIt tool workaround ASAP.
(EDIT: Add final link to MS Blog entry about the FixIt.)

Microsoft today released updates to plug at least 26 separate security holes in its Windows operating systems and related software. At the same time, Microsoft has issued a stopgap fix for a newly-discovered flaw that attackers are actively exploiting.
In a separate advisory published today, Microsoft warned that it is aware of active attacks that leverage a vulnerability in Microsoft XML Core Services 3.0., 4.0, 5.0. and 6.0. This is a browse-and-get-owned flaw that can be triggered when an Internet Explorer user on any supported version of Windows visits a specially crafted Web page. Microsoft does not have an official patch available yet for this flaw, but it has issued a FixIt tool workaround that effectively disables the vulnerable component. The vulnerability was discovered by Google, which said it saw the flaw being exploited in the wild in targeted attacks.
- Google Online Security Blog: Microsoft XML vulnerability under active exploitation
Tuesday, June 12, 2012 12:53 PM
Posted by Andrew Lyons, Security Engineer
Today Microsoft issued a Security Advisory describing a vulnerability in the Microsoft XML component. We discovered this vulnerability—which is leveraged via an uninitialized variable—being actively exploited in the wild for targeted attacks, and we reported it to Microsoft on May 30th. Over the past two weeks, Microsoft has been responsive to the issue and has been working with us. These attacks are being distributed both via malicious web pages intended for Internet Explorer users and through Office documents. Users running Windows XP up to and including Windows 7 are known to be vulnerable.
As part of the advisory, Microsoft suggests installing a Fix it solution that will prevent the exploitation of this vulnerability. We strongly recommend Internet Explorer and Microsoft Office users immediately install the Fix it while Microsoft develops and publishes a final fix as part of a future advisory.

By Ryan Naraine | June 18, 2012, 3:09am PDT
Summary: Microsoft has confirmed that this flaw is being used in “limited attacks” but the company has not (yet) updated its MS12-037 bulletin to make it clear that public exploit code is now widely available.
- ISC Diary | Microsoft Security Advisory 2719615 - MSXML - CVE-2012-1889
Several readers mentioned that Microsoft today issued a Security advisory regarding Microsoft XML Core Services (MSXML). This is in response to active exploitation.
The issues affects Office 2003 and 2007 on all versions of windows. All a user has to do to fall victim is visit the wrong website using IE.
Microsoft has issued a fixit for it in the form of an msi file (see the KB 2719615 link below).
Alternative strategies would be to use browsers that do not support ActiveX, or disable the support in IE.
