cpython: cpython: `tarfile` module misinterprets crafted tar archives leading to data integrity issues

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 block...

Poetry 路径遍历漏洞

Poetry is an open-source Python tool used for dependency management and packaging. Versions of Poetry prior to 2.3.4 contained a path traversal vulnerability. This vulnerability stemmed from the extractall function failing to provide path traversal protection when extracting sdist tarballs on...
