Details

Extract has insufficient checks allowing attacker to create symlinks outside the extraction directory. ### Impact A maliciously crafted archive may allow an attacker to create a symlink outside the extraction target directory. ### Patches Please use version 4.0.0 or later `github.com/codeclysm/extract/v4`. Any previous version is affected by the bug. ### Workarounds No knows workarounds. ### Backward compatibility notes about upgrading to `/v4` from `/v3` If you're not using the `extract.Extractor.FS` interface, you will not face any breaking changes and upgrading should be as simple as changing the import to `/v4`. This should be the case for most of the userbase. If you're using the `Extractor.FS` interface, then upgrading to `/v4` will require to implement the new methods that have been added: ```go type FS interface { Link(string, string) error MkdirAll(string, os.FileMode) error OpenFile(name string, flag int, perm os.FileMode) (*os.File, error) Symlink(string, string) error // The following methods have been added in the /v4 interface: Remove(path string) error Stat(name string) (os.FileInfo, error) Chmod(name string, mode os.FileMode) error } ``` There should be no other breaking changes in the `/v4` API.
