FlexNet License Server Manager lmadmin Remote Code Execution Vulnerability

(0day) FlexNet License Server Manager lmadmin Remote Code Execution Vulnerability

Affected Vendor and Product: Flexera Software’s FlexNet License Server Manager

Vulnerability Details

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Flexera Software Flexnet License Server Manager. Authentication is not required to exploit this vulnerability.

The flaw exists within the lmadmin component which listens by default on TCP port 27000 (this can vary however if the port is in use). When handling a packet type having the opcode 0x2f the process trusts a user provided value when calculating the bytes remaining in the packet. Using this tainted remaining length value the process then copies packet data into a buffer on the heap. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the lmadmin user.

Vendor Response

Flexera Software states:

[July 28, 2011] - This vulnerability is being disclosed publicly without a patch in accordance with the ZDI 180 day deadline.

Mitigation supplied by vendor:
This report has been entered into Flexera Softwares technical support case tracking system as IOC-000086525. The FlexNet License Server Manager components (lmgrd, lmadmin, and each vendor daemon) are only intended to be deployed in networks that are controlled by the recipient of FlexNet-enabled software. In particular, they are not intended to be deployed on the internet or in a public cloud.

Autodesk Acquires Pixlr

What is Pixlr? Here’s what that FAQ says: Pixlr is the creator of online cloud-based image tools and utilities. Today we have three applications in our suite: Pixlr Editor, Pixlr Express and Pixlr-o-matic. They are built in Flash and you need to have the Flash plug-in (get flash) to get it to work, however, 98% of all computers have flash so you are probably set. We also provide screengrabbing tools Pixlr Grabber and one click photo sharing imm.io.

Pixlr Editor

Here’s the press release:

Autodesk Acquires Pixlr
Image Services to Strengthen Autodesk Consumer Product Portfolio

SAN RAFAEL, Calif.--(BUSINESS WIRE)--Autodesk, Inc. (NASDAQ:ADSK), a leader in 3D design, engineering and entertainment software, announced today that it has completed the acquisition of Pixlr, a popular free* online and social image creating, collecting, editing and sharing service. Terms of the transaction were not disclosed.

The Pixlr service was started in Sweden in August 2008 and provides accessible tools for non-professionals to create, edit, and share images online and socially via platforms like Facebook. The acquisition enhances Autodesk’s ability to provide image editing for its consumer products, such as the SketchBook product line. As a result of the acquisition, SketchBook Pro desktop users will gain the ability to read and write image file formats such as PXD and to easily exchange files while maintaining deep data such as layers. Current Pixlr users will immediately be able to add more freehand sketching to their projects through file compatibility with Autodesk SketchBook Pro desktop application.

“Lots of people–not just creative professionals—want to express themselves visually,” said Samir Hanna, vice president of Consumer Products at Autodesk. “Combining image editing capabilities with sketching capabilities provides new avenues for rich visual expression. We also intend to marry the Pixlr team’s web development experience with our expertise in mobile app development to help people everywhere be creative on the devices of their choice.”

Pixlr’s founders are now part of Autodesk.

API enhancements for Windows in KB2533623

With this week’s update you may find the Update for Windows 7 for x64-based Systems (KB2533623) and is available for Windows Vista, Windows Server 2008, Windows 7 and Windows Server 2008 R2.

Microsoft has released new API enhancements for Windows to help developers correctly and securely load external libraries. For more information, visit the following Microsoft webpages describing these three APIs.

SetDefaultDllDirectories
Specifies a default set of directories to search when the calling process loads a DLL. This search path is used when LoadLibraryEx is called with no LOAD_LIBRARY_SEARCH flags.

AddDllDirectory
Adds a directory to the process DLL search path.

RemoveDllDirectory
Removes a directory that was added to the process DLL search path by using AddDllDirectory.

Microsoft has also released a Microsoft security advisory about this issue for IT professionals. The security advisory contains additional security-related information. To view the security advisory, visit the following Microsoft website: http://www.microsoft.com/technet/security/advisory/2269637.mspx

Insecure Library Loading Could Allow Remote Code Execution.

The update in Microsoft Knowledge Base Article 2533623 implements Application Programming Interface (API) enhancements in Windows to help developers correctly and securely load external libraries. This update for Windows is available in the "High Priority" Updates category for customers who have not already received the update through automatic updating.

Developers can help to ensure their programs load DLLs properly to avoid "DLL preloading" or "binary planting" attacks by following the guidance provided in Microsoft Knowledge Base Article 2533623 to take advantage of the API enhancements provided by this update.

Windows Live Essentials 2011 build 15.4.3538.0513

Inside Windows Live informs about the new Windows Live Essentials 2011 build 15.4.3538.0513 released 2011-07-06 and you can get it at http://explore.live.com right now.

Here are a few things mentioned:

  • Mail: We fixed a sorting issue in the Sent items folder and improved the upload reliability and instrumentation in Photo mail.
  • Messenger: We fixed a couple of stability issues and made various changes for improved voice and video quality. We fixed an issue that was causing sound to be lost after upgrading, and we improved performance when displaying the MSN Today page in the main window.
  • Photo Gallery: We implemented various bug fixes for crashes related to launching Photo Gallery through Autoplay and facial recognition.
  • And more: We made many other usability, performance, and stability improvements across the suite of Windows Live Essentials apps.

Unfortunately these other bugs are not fixed yet: Windows Live Writer 2011 picture quality bug and Windows Live Writer 2011 bug and wish.

I had to uninstall the previous version of Windows Live Essentials 2011 due to some problem with Windows Live ID Sign-in Assistant and then I had to restart before succeeding.

If you get this error it might help to just restart the computer: Windows Live Essentials couldn’t be installed. It looks like another program is preventing the installer from working. Error: 0x80070643 Source: wllogin-amd64
