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\", \"<extract_base>/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. This issue is fixed in version 2.6.2."

Antes de la versión 2.6.2, ensureLinkPath en content/file/utils.go:262-275 valida un objetivo de enlace duro relativo a la base de extracción pero devuelve el objetivo sin resolver, lo que provoca que os.Link(’victim.secret’, ’[extract_base]/payload.tar.gz/evil_cwd_link’) resuelva header.Linkname contra el directorio de trabajo actual del proceso para una entrada Typeflag=TypeLink como Name=payload.tar.gz/evil_cwd_link y Linkname=’victim.secret’ con io.deis.oras.content.unpack: ’true’, lo que puede exponer o manipular archivos como .env, .git/config, .aws/credentials y ~/.ssh/config. Este problema está solucionado en la versión 2.6.2."
