{"id":"CLSA-2026-1789636518","summary":"Fix CVE(s): CVE-2026-11972, CVE-2026-9669","details":"   * SECURITY UPDATE: quadratic parse time in the tarfile module when a\n     streaming archive declares an offset past the end of the stream\n     - debian/patches/CVE-2026-11972.patch: stop the forward-seek loop in\n       _Stream.seek() as soon as read() returns no data, in Lib/tarfile.py,\n       so a crafted mode=\"r|\" archive can no longer keep the parser reading\n       an exhausted stream.\n     - CVE-2026-11972\n   * SECURITY UPDATE: out-of-bounds write when a bz2 decompressor is reused\n     after a decompression error\n     - debian/patches/CVE-2026-9669.patch: record the libbzip2 error in the\n       BZ2Decompressor object and refuse any further decompress() call with\n       ValueError, in Modules/_bz2module.c, so retrying with the same object\n       can no longer re-enter BZ2_bzDecompress() on a bz_stream left in an\n       invalid internal state.\n     -
