Adobe Shockwave Player: Critical Security Update to v11.6.4.634

--
Adobe has again done the right thing and ignored their own idiotic quarterly updates schedule. I'm glad someone over there has a brain in their head. This time the problem is with Adobe Shockwave Player. Adobe says:
These vulnerabilities could allow an attacker, who successfully exploits these vulnerabilities, to run malicious code on the affected system.
Update Adobe Shockwave Player to version 11.6.4.634 immediately. You can download it here:

A good article about the many dangerous security flaws in the previous version is available at ZDNet:


You can read Adobe's detailed explanation of the critical security issues here:


And for those interested: 
ALL the critical security flaws are due to poor memory management, still the bane of modern code engineering. (o_0)

Adobe CRITICAL Security Updates for August!

Adobe released another slew of 'Critical' security updates today. Here's the lineup:

- Adobe Shockwave Player - Update to v11.6.1.629. (Be careful which version you install, either 32-bit or 64-bit, to match the bit mode being used by your web browsers. If one version fails, uninstall it and try the other). Numerous memory corruption (buffer overflow) vulnerabilities.

- Adobe Flash Media Server - Update to v4.0.3 or v3.5.7. Memory corruption (buffer overflow) vulnerability.

- Adobe AIR - Update to version v2.7.1. (Apparently required as part of the Adobe Flash Player update).

- Adobe Flash Player - Update to v10.3.186.5. Numerous memory corruption (buffer overflow) vulnerabilities and a cross-site information disclosure vulnerability.

- Adobe Photoshop CS5 - Update via CS5/CS5.1 Standard Multiplugin Update. Malicious GIF file vulnerability.

- Adobe RoboHelp / RoboHelp Server - RoboHelp v9.0.1.262 users are NOT vulnerable. Earlier RoboHelp 9 users update via APSB11-23_1.zip. RoboHelp 8 users update via APSB11-23_2.zip. Cross-site scripting attack vulnerability.

Adobe 'Out Of Band' CRITICAL Update Parade:
Shockwave Player v11.5.8.612

--
Adobe continues their parade of CRITICAL security updates with Shockwave Player v11.5.8.612. Thankfully, you only have to make one click on one page to download it. (Someone over there is getting the clue). And get this! (Don't go into shock!) It's 64-bit! Here is the download page link:

Shockwave Player v11.5.8.612

You can read about the security patches HERE.

To quote Adobe:
The vulnerabilities could allow an attacker, who successfully exploits these vulnerabilities, to run malicious code on the affected system.
My quick summary:

There are 20 security patches.

-> 16 patches are for memory corruption vulnerabilities (aka buffer overflow bugs).

-> 2 patches are for DOS (denial of service) attack issues.

-> 1 patch is for a pointer offset vulnerability.

-> 1 patch is for an integer overflow vulnerability (aka buffer...).

The update is for both Mac and Windows versions. Adobe don't note any in-the-wild exploits at this point. But as per usual, keep up to date with App and OS security patches!

Apple Security Update 2010-005

--
Apple have released FOUR versions of Security Update 2010-005. The versions are linked below:

Mac OS X Snow Leopard Client - 80.63 MB

Mac OS X Snow Leopard Server - 136.86 MB

Mac OS X Leopard Client - 211.88 MB

Mac OS X Leopard Server - 418.92 MB

The general downloads page can be found HERE.

You can read about the security patches HERE.

My quick summary:

There are 8 security patches.

-> 2 PHP patches: One patches a buffer overflow vulnerability regarding maliciously crafted PNG image files. The other updates PHP to version v5.3.2, which itself provides a variety of security patches to such things as further buffer overflow vulnerabilities.

-> 1 Samba patch: A buffer overflow...

-> 1 Apple Type Services (ATS) patch: A vulnerability to maliciously crafted embedded fonts due to a buffer overflow...

-> 1 CFNetwork patch: Prevents a man-in-the-middle attack that could redirect network connections and intercept a user's sensitive information such as their user credentials.

-> 1 ClamAV patch: Updates the versions of ClamAV in Mac OS X Server 10.5 and 10.6 to version 0.96.1, solving multiple vulnerabilities.

-> 1 CoreGraphics patch: A heap buffer overflow due to maliciously crafted PDF files. (Presumably this is related to a similar problem in iOS v4.0).

-> 1 libsecurity patch: Improves the handling of certificate host names, preventing a website impersonation attack.

Adobe 'Out Of Band' CRITICAL Updates Parade:
Acrobat and Reader v9.3.4

--
And the parade marches on. At last we have the latest in CRITICAL Adobe security hole updates. This time the updates are for Adobe Acrobat and Adobe Reader. GET THEM NOW!

Because the process of getting to actual download links at the Adobe site is a huge PITA, here are direct URLs for English Intel Mac users. Send me virtual luv:

Acrobat Reader v9.3.4 update

Adobe Acrobat 9.3.4 Pro update

The general update page for all other users and versions is HERE.

What's so CRITICAL? The update's security bulletin is HERE.

To quote Adobe:

These updates address CVE-2010-2862, which was discussed at the Black Hat USA 2010 security conference on Wednesday, July 28, 2010. They also incorporate the Adobe Flash Player update as noted in Security Bulletin APSB10-16.
My summary:

1) The updates patch memory corruption vulnerabilities that could lead to hacked code execution on your Mac and/or program crashes. IOW its more of the same old buffer overflow problem that plagues current computer coding in general. (As found in CVE-2010-2862).

Quoting from the CVE:

Integer overflow in CoolType.dll in Adobe Reader 8.2.3 and 9.3.3, and Acrobat 9.3.3, allows remote attackers to execute arbitrary code via a TrueType font with a large maxCompositePoints value in a Maximum Profile (maxp) table.

2) They solve a social engineering attack security hole via PDF files that could lead to hacked code execution on your Mac. (As found in CVE-2010-1240).

Quoting from the CVE:

Adobe Reader and Acrobat 9.x before 9.3.3, and 8.x before 8.2.3 on Windows and Mac OS X, do not restrict the contents of one text field in the Launch File warning dialog, which makes it easier for remote attackers to trick users into executing an arbitrary local program that was specified in a PDF document, as demonstrated by a text field that claims that the Open button will enable the user to read an encrypted message.
~~~~~~~~~~

BTW: Looking up CVE reports is easy, if snooze inducing. Just go to the National Vulnerability Database site (at the National Institute of Standards and Technology) and search on the CVE number. Here is the URL to get you started:

National Vulnerability Database (NVD) Search Vulnerabilities

And now for a rant:

If you're wondering why these simple and specific CVE searches take a long time (zzzzz) to resolve, it's the decrepit US government. It's Microsoft Windows. It's ancient old PCs the government is too cheap to replace, cranking away on stuff that takes any modern Mac a microsecond. (But of course, the government did manage to fund the infamous 'Bridge To Nowhere' in Alaska, hardy har har, porky pork, oinky oink, so long Ted Stevens you parasite).

I was once offered a job at the Department of Wildlife. I took one look at their computers and wondered what would be the appropriate response: Running away screaming OR sauntering out laughing?

In any case, if you've ever wondered why it's so incredibly easy for The Red Hacker Alliance in Red China and other such scum to hack into US government computers, look no further for your answer. Much as I hated the Bush League, much as I'd like to support the Obama Era, this stupid state of affairs continues. Note the fact that the Obama Administration hired ex-Microsoft executives and coders to help them solve their computer security crisis. That's right! They hired the CAUSE of the problem to SOLVE the problem.

Hmm. What would be the appropriate response? I'll leave it to you to decide.

CUL8R!
Stay safe.
Stay secure.

Update:
Secunia Half Year Report 2010
& QuickTime Hell

--
In a previous article, entitled "Desperate Propaganda..." I had a rant-fest regarding a PC World FUD-fest regarding Apple security. The author, Preston Gralla, managed to spew out this line of deceit:

:-Q****** "The security company Secunia reports that Apple products have more vulnerabilities than those of any other company."

This was clearly taken as a hit at all Apple products. What was missing was any reference to the context of the source Secunia report, which you can read HERE. I knew better, having been an avid Secunia reader since 2005. In fact, the only Apple products noted in the report were QuickTime and iTunes on Microsoft Windows. Secunia didn't cover any other Apple products.

When I read through the entire Secunia Report I found nothing of relevance to Mac OS X except the fact that the Apple apps discussed are prone to the same problems on Mac OS X as well as Windows.

QuickTime Hell

In previous articles I've covered the major problems with QuickTime, the biggest culprit of Apple security holes. It is used in iTunes, thus making iTunes just as vulnerable. In summary, QuickTime stumbles over malicious ECMAScript (aka 'JavaScript') and coding errors that allow malicious buffer overflows.

Supposedly Apple has been overhauling QuickTime. The first peak at it has been QuickTime Player X. But as far as any user can tell, the QuickTime X project is stalled at version 1.0.0. What we have on Snow Leopard is entirely inadequate, incomplete and buggy. Serious QuickTime users are required to also install QuickTime version 7, the current version of which is 7.6.6.

Hopefully Apple will get back to work on revising QuickTime now that iOS 4 has been completed and released.

Mac Security Update 2009-001, Java Updates and a Safari for Windows Update

--
If you'd like to read Apple's notes about Security Update 2009-001, you can click HERE.

Ahead is a quick analysis of what is covered in the update, along with comments.

This security update is specifically for computers updated to Mac OS X 10.4.11 and 10.5.6, both client and server. Presumably it will be integrated into 10.5.7 when it's available.

There are 28 specific security updates including fixes for 48 documented vulnerabilities, making this another whopper relative to the updates we used to get from Apple a couple years back. I like that. The updates cover some interesting aspects of the Mac OS X Apple have not previously addressed. This indicates to me that over time they are carefully combing through aspects of the OS rather than randomly poking around or only responding as they receive vulnerability reports from third parties.

As ever, there are several buffer overflow patches. Memory management remains one of the banes of contemporary coding. I'm getting the idea that this problem won't go away until we invent an AI that can self-analyze its own computer code. It could happen!

A surprising trend in this update is the patching of security problems introduced specifically in Mac OS X 10.5.6. Ahem Apple. Ahem beta testers.

Cookies: There are a couple repairs for cookie problems introduced into the CFNetwork process in Mac OS X 10.5.6.

Printing: Included is a CUPS update as well as a repair of an error in the csregprinter process that allowed system privileges escalation.

Scripting: There are several patches provided for python and one for perl.

Remote Apple Events: There are a couple buffer overflow / out-of-bounds memory access patches.

SMB: Apple themselves patched a couple buffer problems, which is interesting. It's good to see Apple serious about compatibility with Windows networks.

X11: There are a collection of patches regarding font handling, user privilege plundering and several other vulnerabilites in the X11 server.

JavaScript: Here's another bane of contemporary coding. This time the patch is to Safari's RSS handling of feed URLs.

Mail services: A pair of patches are made to fetchmail and another pair to SquirrelMail.

Video: Yet another problem with maliciously crafted media files. This time a patch is provided for the Pixlet codec.

Other patched services include:

AFP Server
CarbonCore's Resource Manager
Certificate Assistant
CoreText
DS Tools: dscl
Folder Manager
FSEvents framework: fseventsd
Network Time
Server Manager: servermgrd
XTerm

And included is a security updated version of ClamAV for both 10.4 and 10.5 Server.

There were also a few other security related updates released today. Here is a list with links provided to their individual security update description documents:

Safari 3.2.2 for Windows

Java for Mac OS X 10.4 Release 8

Java for Mac OS X 10.5 Update 3

The Java security vulnerabilities that were patched include maliciously written web page Java applets allowing user privilege plundering. These problems weren't in Apple's implementation but in Java itself. SOS: Java was supposed to be as safe as a sandbox. Yeah, a sandbox full of land sharks.

My recommendation for security fanatics, as per recommendations from security expert Steve Gibson: If you don't want to take chances with hacker perpetrated JavaScript and Java, use a browser that lets you turn on support for both protocols on a site by site basis. As with using Little Snitch, it can be a PITA dithering around with little stuff on the net. But the geek in me adjusted such that I use site by site service control all the time. The browser I use for this purpose is OmniWeb. It's the bells and whistles web browser for Mac OS X and is well worth paying for if you like its abundant added features. You can also rig FireFox to handle site by site services as well. Camino and Safari are sadly site specific clueless. I haven't tested other browsers.

BTW: Coming up is my long delayed discussion of Tracking Cookies.

Share and Enjoy!
