Photoshop CS4 to be 64-bit for Windows, but not Mac

Adobe’s flagship product, Photoshop, will become a 64-bit application in the next major revision to the company’s bundle of creative pro applications, Creative Suite 4. However, the 64-bit version will only be available to Windows users because of a change Apple made at its Worldwide Developers Conference (WWDC) in 2007.

The good news is that Adobe will make a 64-bit version for the Mac in the future.

“We can reassure people that literally from the day we found out Carbon 64-bit was cancelled, we have been figuring out what we need to do to get there,” John Nack, senior product manager for Adobe Photoshop, told Macworld.

At WWDC 2007 Apple discontinued its Carbon 64-bit program, which left company’s like Adobe without an avenue to make its current codebase 64-bit. What Adobe has to do now is transition all of the old Photoshop code to Apple’s native Cocoa programming language, where it can then be made 64-bit.

“If you want to go 64-bit on the Mac, you have to port to Cocoa and that’s not a trivial task,” said Nack.

Adobe said that they have been working on the Carbon 64-bit version of Photoshop for some time and had planned on releasing a version for Creative Suite 4 (CS4). However, with the changes at WWDC 2007, that is not going to happen.

“Our feeling has been to deliver 64-bit on both platforms for this release,” said Nack. “We could hold back the Windows 64-bit version until we could catch up on the Mac, but that didn’t seem fair to those customers.”

If one good thing can come out of the delay, Nack says Adobe will gain valuable experience in writing 64-bit applications, albeit for Windows.

Windows Users Not Vulnerable To PDF Flaw

The recently reported flaws discovered in Reader and Acrobat tools urged Adobe, the developer of the vulnerable solutions, to release patches in order to protect the customers of the company. If you haven’t read the advisories, you should know the holes affected Windows XP users with Internet Explorer 7 installed because the attackers tried to exploit them using malicious PDF files. According to Adobe which confirmed the existence of the flaws, the vulnerabilities affect Adobe Reader 8.1 and earlier, Adobe Reader 7.0.9 and earlier, Adobe Acrobat Professional, 3D and Standard 8.1 and earlier versions, Adobe Acrobat Professional, Standard, 3D and Elements 7.0.9 and earlier.

In order to avoid a successful exploitation of the flaw, you have to update your technologies to version 8.1.1 as Adobe implemented the patches in this latest release. (more…)

Adobe Reader and Acrobat Allow Attacks via PDFs

Severity: Medium

22 October, 2007

Summary:

Yesterday, Adobe released an update to fix critical security vulnerabilities that affect Adobe Reader 8.1 and Adobe Acrobat 8.1 (and all earlier versions) running on Windows XP. By enticing one of your users into opening a specially crafted PDF file, an attacker can exploit the worst of these flaws to gain control of that user’s system. If you use Adobe Reader or Acrobat in your network, you should download, test, and deploy version 8.1.1 as soon as possible.

Exposure:

In a security bulletin released yesterday, Adobe warned of several critical vulnerabilities in Reader 8.1 and Acrobat 8.1 (and all earlier versions) for Windows XP. While their advisory regularly mentions multiple vulnerabilities, they specifically refer to only one issue, which they describe in little detail. Adobe only says that if an attacker can convince a Windows XP user who also has Internet Explorer (IE) 7 into opening a specially crafted PDF file, the attacker can exploit this unspecified flaw to gain control of that user’s computer. Since you can embed PDF files into Web pages, simply visiting the wrong web page might trigger this flaw.

Petko D. Petkov (aka pdp) of GNUCITIZEN.org, first discovered this flaw last September. Following the tenets of responsible disclosure, he did not release any details about this flaw, instead waiting for Adobe to release a patch. However, he also promised to release Proof-of-Concept (PoC) code that demonstrates this flaw in action as soon as Adobe released their update. So expect to see exploits for this vulnerability shortly. Adobe users should upgrade as soon as possible.

Solution Path

Adobe Reader 8.1.1 and Acrobat 8.1.1 fix these vulnerabilities. Windows XP administrators should download, test, and deploy these updates as soon as possible.

For All WatchGuard Users:

Although many of WatchGuard’s Firebox models can block incoming PDF files, most administrators prefer to allow these file types for business purposes. You should download and install Adobe Reader 8.1.1 instead.

However, if you still want to block .PDF files, follow the links below for instructions:

  • Vclass
    • SMTP Proxy. You’ll have to create or adjust a custom proxy action based on SMTP-Incoming in order to strip .PDF files. If you have created your own Proxy Action based on SMTP-Incoming, you can edit it so that it blocks these files. In the Vcontroller software, click the Proxies button and double-click your custom proxy action. Under the Content Checking tab, change “Category” to Attachment Filename and click either the Add to Top or Insert After button (only one or the other will display). Next, type “PDF_files” as the new rule’s name, and choose Pattern Match. Next to Pattern Match, type “*.PDF” and select Strip as the Action. Now you can apply this new Proxy Action to your SMTP rule to ensure your Firebox blocks .PDF files.

 

  •  
    • HTTP Proxy. You’ll have to create or adjust a custom proxy action based on HTTP-Outgoing in order to strip .PDF files. If you have created your own Proxy Action based on HTTP-Outgoing, you can edit it so that it blocks these files. In the Vcontroller software, click the Proxies button and double-click your custom proxy action. Under the Request General tab, change “Category” to URL Paths and click on Add. Next, type “PDF_files” as the new rule’s name, and choose Pattern Match. Next to Pattern Match, type “*.PDF” and select Strip as the Action. Now you can apply this new Proxy Action to your HTTP rule to ensure your Firebox blocks .PDF files.

Status:

Adobe released Adobe Reader 8.1.1 and Acrobat 8.1.1 to correct these issues.

Adobe Admits to Serious Vulnerability

Adobe

About three weeks ago, word of an Adobe security flaw began to do the rounds.  It has taken Adobe three weeks to finally get around to announcing the problem.  The vulnerability allows a hacker to take control of a Windows XP system if it has IE7 installed.  Considering the amount of people that run IE7, it is probably quite a lot of systems.

The vulnerability exists in Adobe Reader 8.1 (and previous versions) Acrobat Standard, Professional and Elements 8.1 (and previous versions) and Acrobat 3D.  It is the reader vulnerability that makes this a particularly serious threat as the number of people using Acrobat is somewhat limited.  What machine doesn’t have a copy of Adobe Reader installed? It is free and PDF is the format of choice for a lot of written material online.

Adobe has released a temporary solution.  It involves making modifications to the Windows Registry, which tends to frighten away all but the power users.  The good news is that a real fix is on the way and should be here before the end of October.  Expect to see more of this type of vulnerability appearing in other programs and be careful where you click.
