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
