CVE-2025-13462

The "tarfile" module would still apply normalization of AREGTYPE (\x00) blocks to DIRTYPE, even while processing a multi-block member such as GNUTYPE_LONGNAME or GNUTYPE_LONGLINK. This could result in a crafted tar archive being misinterpreted by the tarfile module compared to other implementations.

Summary		(es) El módulo 'tarfile' seguiría aplicando la normalización de bloques AREGTYPE (\x00) a DIRTYPE, incluso al procesar un miembro de múltiples bloques como GNUTYPE_LONGNAME o GNUTYPE_LONGLINK. Esto podría resultar en un archivo tar manipulado siendo malinterpretado por el módulo tarfile en comparación con otras implementaciones.
