This PR aims to fix #407 (reserved as
CVE-2023-0475), by introducing "(de)compression" bomb mitigation options to the various decompressors provided by this package. Specifically,FileSizeLimitandFilesLimit.FileSizeLimitlimits the size of a decompressed file, or limits the total size of all decompressed files if dealing with an archive.FilesLimitlimits the number of files that are allowed to be decompressed from an archive.There are a few downsides to consider with the current approach I've taken before we merge this PR:
io.LimitReaderreturns anEOFafter the configured byte limit, and doesn't seem to provide a clear "you've read past the limit" error. In certain situations, this might lead to an unintended silent error.☝️ To mitigate some of those issues, for the ZIP and TAR archives, I use the
FileInfoin the header returned for the content to check the size before using it.
