CVE-2025-13462  (opens in a new tab)

How to fix?

Upgrade Ubuntu:24.04 python3.12 to version 3.12.3-1ubuntu0.15 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream python3.12 package and not the python3.12 package as distributed by Ubuntu. See How to fix? for Ubuntu:24.04 relevant fixed versions and status.

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.
