Description:
* SECURITY UPDATE: out-of-bounds write via bz2 stream reuse after a decompression error (CVE-2026-9669) - debian/patches/CVE-2026-9669.patch: record the libbz2 error code on the BZ2Decompressor and BZ2File objects in Modules/bz2module.c and refuse every later decompress() or read() call, so BZ2_bzDecompress() is never re-entered on a stream libbz2 has already reported an error for; adds regression tests for both paths to Lib/test/test_bz2.py - CVE-2026-9669
