WinZip 9.0 Service Release 1 (SR-1)
WinZip 9.0 Service Release 1 (SR-1) is a maintenance release of WinZip 9.0 containing important security-related fixes and improvements to WinZip. It was posted on the WinZip web site on August 26, 2004.
The main changes in WinZip 9.0 SR-1 include:
- A number of general internal improvements have been made to the WinZip program to enhance security and reliability. In the course of its internal review and testing, WinZip Computing also identified and addressed some specific cases where security vulnerabilities, including potential buffer overflows, existed in previous versions of WinZip.
- WinZip 9.0 SR-1 also addresses a buffer overflow issue privately reported by a WinZip user that could be triggered by specially-crafted invalid input on the WinZip command line.
- The main visible change in WinZip 9.0 SR-1 is that WinZip now displays caution messages in some situations, such as when a user double-clicks on a .EXE file compressed within a Zip file, to warn that the compressed file has a file type that could potentially contain a virus. WinZip users who frequently need to work with the file types involved can easily turn the caution messages off.
