Photoshop CS5 and CS5.1 for Windows and Mac OS
This update addresses vulnerabilities that could allow an attacker to take control of the affected system. For an attacker to exploit these vulnerabilities, a user must open a malicious TIF or DAE file in Photoshop CS5.1, Photoshop CS5, and earlier. Adobe is not aware of any attacks exploiting these vulnerabilities against Adobe Photoshop.
If you have Photoshop CS5, only download and install the 12.0.5 update. If you have Photoshop CS5.1, only download and install the 12.1.1 update.
If you're installing the update on Windows, unzip the file you've downloaded by using a utility such as WinZip or PKZIP.
This updater updates only the retail version of Adobe Photoshop CS5 or CS5.1 and not any prerelease (beta) versions. To confirm that the updater has run successfully, launch Photoshop. Verify that the version number on the startup screen shows 12.0.5 and not 12.0.0 for Photoshop CS5, or shows 12.1.1 and not 12.1.0 for Photoshop CS5.1. If it does not show correctly, it's possible that you don't have a retail version of Photoshop CS5. Contact your local Adobe retailer or visit the Adobe website to purchase one.
