LOWCVSS 2/10EPSS 0.16%

Last modified

CVE-2025-13462 is a low-severity vulnerability rated 2/10 on the CVSS scale. 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.. EPSS estimates a 0.16% chance of exploitation in the next 30 days.
