CLSA-2026-1789900651 Fix CVE(s): CVE-2026-11972, CVE-2026-9669

SECURITY UPDATE: CPU denial-of-service in tarfile streaming mode via a crafted archive that declares more blocks than it contains - debian/patches/CVE-2026-11972.patch: in Lib/tarfile.py, break out of the block loop in Stream.seek once read returns no data, so an archive opened in streaming mode...

python: Python tarfile module: Denial of Service via improper EOF handling in streaming mode

A flaw was found in the Python tarfile module. When processing a specially crafted tar archive opened in 'streaming mode' mode='r|', the module does not properly handle the end-of-file EOF condition. This can cause the tarfile module to enter an infinite loop, leading to a Denial of Service DoS f...
