GHSA-9QPV-486P-2V4H

Vulnerability from github – Published: 2026-03-12 18:30 – Updated: 2026-03-13 21:31

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.

Severity ?

2.0 (Low)
