Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link(\"victim.secret\", \"\u003cextract_base\u003e/payload.tar.gz/evil_cwd_link\") to resolve header.Linkname against the process current working directory for a Typeflag=TypeLink entry such as Name=payload.tar.gz/evil_cwd_link and Linkname=\"victim.secret\" with io.deis.oras.content.unpack: \"true\", which can expose or tamper with files such as .env, .git/config, .aws/credentials, and ~/.ssh/config.
