EPSS 0.02%tarfile: Skip DIRTYPE normalization during GNU LONGNAME/LONGLINK handling
發布日:2026/3/12修改日:2026/5/16
描述
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.
