(with a filename) Version 2.5.0+ Updates Minimum OS Versions
A key dependency of this project is the zlib library. zlib before version 1.2.12 allows memory corruption when deflating (i.e., when compressing) if the input has many distant matches according to CVE-2018-25032.
zlib 1.2.12 is included in macOS 10.15+ (with latest security patches), iOS 15.5+, tvOS 15.4+, watchOS 8.4+. As such, these OS versions will be the new minimums as of version 2.5.0 of ZipArchive.
