  "details" : [ "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.", "A flaw was found in the `tarfile` module of cpython. This vulnerability allows a remote attacker to craft a malicious tar archive that, when processed, could be misinterpreted by the `tarfile` module. This misinterpretation occurs because the module incorrectly applies normalization of `AREGTYPE` blocks to `DIRTYPE` during the processing of multi-block members, such as `GNUTYPE_LONGNAME` or `GNUTYPE_LONGLINK`. The consequence is that the `tarfile` module may process the archive differently than intended, potentially leading to unexpected file system changes or data integrity issues." ],
