add\n       regression test to Lib/test/test_tarfile.py\n     - CVE-2026-11972\n   * SECURITY UPDATE: Out-of-bounds write when a bz2 decompressor or a BZ2File\n     handle is reused after a decompression error\n     - debian/patches/CVE-2026-9669.patch: record the failing libbz2 error\n       code on BZ2DecompObject and refuse any further decompress() call with\n       ValueError in Modules/bz2module.c, so crafted input can no longer make\n       BZ2_bzDecompress() resume from an invalid internal state and write out\n       of bounds to a stack buffer; also make the error sticky for the C\n       BZ2File read paths, which re-entered the errored stream in the same\n       way; add regression tests for both to Lib/test/test_bz2.py\n     - CVE-2026-9669","modified":"2026-10-26T09:31:40.157576388Z","published":"2026-09-22T10:18:43Z","upstream":["CVE-2026-11972","CVE-2026-9669"],"references":[{"type":"ADVISORY","url":"https://errata.tuxcare.com/els_os/ubuntu20.04els/CLSA-2026-1790072312.html"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-11972"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-9669"}],"affected":[{"package":{"name":"idle-python2.7","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/idle-python2.7?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"libpython2.7","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/libpython2.7?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"libpython2.7-dev","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/libpython2.7-dev?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"libpython2.7-minimal","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/libpython2.7-minimal?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"libpython2.7-stdlib","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/libpython2.7-stdlib?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"libpython2.7-testsuite","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/libpython2.7-testsuite?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"python2.7","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/python2.7?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"python2.7-dev","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/python2.7-dev?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"python2.7-doc","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/python2.7-doc?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"python2.7-examples","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/python2.7-examples?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}},{"package":{"name":"python2.7-minimal","ecosystem":"TuxCare:Ubuntu:20.04","purl":"pkg:deb/tuxcare/python2.7-minimal?distro=ubuntu-20.04"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.18-1~20.04.7+tuxcare.els7"}]}],"database_specific":{"source":"https://github.com/cloudlinux/tuxcare-osv/tree/main/data/els_os/ubuntu20.04els/CLSA-2026-1790072312.json"}}],"schema_version":"1.9.0"}
