Fix CVE(s): CVE-2024-0397, CVE-2025-8194
Type: advisorySources: OSV
* SECURITY UPDATE: infinite loop and deadlock when parsing tar archives with negative member offsets - debian/patches/CVE-2025-8194.patch: reject negative byte counts in TarInfo._block() with InvalidHeaderError in Lib/tarfile.py, so a crafted negative member size can no longer move the read offset backwards; add regression tests to Lib/test/test_tarfile.py - CVE-2025-8194 * SECURITY UPDATE: memory race condition in ssl.SSLContext cert_store_stats() and get_ca_certs() - debian/patches/CVE-2024-0397.patch: add an X509_STORE_get1_objects() shim that takes a locked deep copy of the certificate store objects and use it in cert_store_stats() and get_ca_certs() in Modules/_ssl.c, so certificates loaded concurrently can no longer free objects that are being iterated - CVE-2024-0397
