WinZip 11.2 SR-1 (Build 8261)
Q: What is WinZip 11.2 SR-1?
A: On September 25, 2008, WinZip® Computing released WinZip 11.2 SR-1, a critical update to all installations of WinZip 11. WinZip 11.2 SR-1 is a free update for registered users of versions 11.0, 11.1 and 11.2.
This release addresses a security vulnerability that exists in one of the modules shipped with WinZip 11. This component is not a WinZip module but rather a Microsoft module that WinZip Computing shipped for the convenience of our Windows 2000 customers.
Distribution files for WinZip versions 11.1 and 11.2 included an earlier gdiplus.dll which was placed in the WinZip program folder for Windows 2000 systems only. Other operating systems are not affected by these installations. Upgrading to WinZip 11.2 SR-1 or WinZip 18.5 on Windows 2000 systems will replace the earlier gdiplus.dll with a newer version that is not subject to the security vulnerability.
Distribution files for WinZip version 11.0 included an earlier gdiplus.dll which was placed in the WinZip program folder without regard to operating system. Note, however, that the .DLL is only utilized by WinZip on Windows 2000 systems. Versions of WinZip prior to 11.0 are not affected by this security vulnerability. Upgrading to WinZip 11.2 SR-1 (Build 8261) or WinZip 18.5 will remove the earlier gdiplus.dll from the WinZip program folder on Windows XP or Vista systems.
On Windows XP or Vista, you may simply delete the file from the WinZip folder (if it exists).
WinZip's use of GDI+ technology is limited to viewing image files in Zip archives when the view mode is set to an Explorer Style/Thumbnail view or when using the internal image viewer (WinZip Pro feature).
Q: How do I get WinZip 11.2 SR-1?
A: You can simply download and install WinZip 11.2 SR-1 over your existing WinZip 11 installation. In order to preserve your existing WinZip registration information, please do NOT uninstall your current WinZip 11 before installing this new version of WinZip 11.
Q: How do I know what version of WinZip I have installed?
A: You can see the version and build number on your screen in the area indicated with the red oval.
If you have WinZip 10.0 or earlier, you are not affected by this particular vulnerability. However this may be a good time to upgrade to WinZip 18.5 and enjoy its new powerful features. Please see the WinZip upgrade information page for details.
