{"schemaVersion":3,"id":"SUSE-SU-2023:0707-1","aliases":[],"status":"published","duplicateOf":null,"title":null,"description":"Security update for python39\n\nThis update for python39 fixes the following issues:\n\n- CVE-2023-24329: Fixed blocklists bypass via the urllib.parse component when supplying a URL that starts with blank characters (bsc#1208471).\n\nUpdate to 3.9.16:\n- python -m http.server no longer allows terminal control\n  characters sent within a garbage request to be printed to the\n  stderr server log.\n  This is done by changing the http.server\n  BaseHTTPRequestHandler .log_message method to replace control\n  characters with a \\xHH hex escape before printing.\n- Avoid publishing list of active per-interpreter audit hooks\n  via the gc module\n- The IDNA codec decoder used on DNS hostnames by socket or\n  asyncio related name resolution functions no longer involves\n  a quadratic algorithm. This prevents a potential CPU denial\n  of service if an out-of-spec excessive length hostname\n  involving bidirectional characters were decoded. Some\n  protocols such as urllib http 3xx redirects potentially allow\n  for an attacker to supply such a name (CVE-2015-20107).\n- Update bundled libexpat to 2.5.0\n- Port XKCP’s fix for the buffer overflows in SHA-3\n  (CVE-2022-37454).\n- On Linux the multiprocessing module returns to using\n  filesystem backed unix domain sockets for communication with\n  the forkserver process instead of the Linux abstract socket\n  namespace. Only code that chooses to use the “forkserver”\n  start method is affected.\n  Abstract sockets have no permissions and could allow any\n  user on the system in the same network namespace (often\n  the whole system) to inject code into the multiprocessing\n  forkserver process. This was a potential privilege\n  escalation. Filesystem based socket permissions restrict this\n  to the forkserver process user as was the default in Python\n  3.8 and earlier.\n  This prevents Linux CVE-2022-42919.\n- The deprecated mailcap module now refuses to inject unsafe\n  text (filenames, MIME types, parameters) into shell\n  commands. Instead of using such text, it will warn and act\n  as if a match was not found (or for test commands, as if the\n  test failed).","dates":{"published":"2023-03-10T13:19:51.000Z","modified":"2025-05-02T04:29:38.585Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"opensuse","product":"python39-core&distro=openSUSE
