The folks at Adobe have been keeping themselves busy this week patching several security holes in their software, including one affecting Photoshop Mac users.

According to a recent technical note on Adobe's site, those using the company’s professional photo editing software on a Mac are advised to patch immediately using Photoshop Standard Multiplugin CS5/CS5.1.

Adobe has recently learned that opening a GIF image of unknown origin may have a negative outcome. Here’s the situation in the Flash maker’s own words:

“The standard multiplugin update addresses a security vulnerability in the GIF file format, where opening a malicious GIF file would cause the application to crash.”

“This update is recommended for anyone who opens GIF files in Photoshop,” Adobe says.

Surely those editing multiple pictures at the same time would hate to see Photoshop crash before them simply because they opened a GIF image.

As such, the 4MB patch is immediately downloadable from Adobe, as well as from Softpedia using the link below.

Download Photoshop Standard Multiplugin CS5/CS5.1 (Free)

It works on systems running Mac OS X 10.5.7 (Leopard) and Mac OS X 10.6 (Snow Leopard) and it applies to one of the following language versions of Photoshop CS5 or Photoshop CS5.1: English, French, Spanish, Portuguese, German, Italian, Dutch, Swedish, Danish, Finnish, Norwegian, Chinese Simplified, Chinese Traditional, Korean, Japanese, Czech, Polish, Russian, Turkish, Hungarian, Ukrainian, or Romanian.

After downloading the ".zip" file containing the Photoshop CS5/CS5.1 Standard Multiplugin Update, Mac users must decompress the contained file and drag it to a specific location where Photoshop is installed.

The full set of instructions, as posted on Adobe’s web site, follows below:

1. Download plugin update 2. Unzip plugin update 3. Open Unzipped plugin folder 4. Drag and drop (or copy and paste) Standard Multiplugin.plugin to Applications\Adobe Photoshop CS5 (or CS5.1)\Plug-ins\Filters 5. Replace the existing file(s) when prompted 6. Relaunch PS
