{"id":"CLSA-2026-1790593993","summary":"Fix of 5 CVEs","details":"   * SECURITY UPDATE: NULL pointer dereference in ngx_mail_auth_http_module\n     when a CRAM-MD5 or APOP authentication attempt is retried\n     - debian/patches/CVE-2026-27651.patch: clear s-\u003epasswd with\n       ngx_str_null() in ngx_mail_auth_http_create_request, so the stale\n       length no longer survives into the next auth attempt and terminates\n       the worker process\n     - CVE-2026-27651\n   * SECURITY UPDATE: heap buffer overflow in ngx_http_dav_module on COPY\n     and MOVE inside an aliased prefix location\n     - debian/patches/CVE-2026-27654.patch: reject a Destination URI\n       shorter than clcf-\u003ealias in ngx_http_dav_copy_move_handler, so the\n       integer underflow in ngx_http_map_uri_to_path can no longer\n       overwrite the heap or move files outside the location root\n     - debian/patches/CVE-2026-27654-2.patch: also require the Destination\n       URI to match the aliased location prefix, and add the corresponding\n       check to ngx_http_map_uri_to_path\n     - CVE-2026-27654\n   * SECURITY UPDATE: integer overflow in ngx_http_mp4_module on 32-bit\n     platforms while validating atom entry counts\n     - debian/patches/CVE-2026-27784.patch: widen the entries count to\n       uint64_t in the stts, stss, ctts, stsc, stsz, stco and co64 atom\n       size checks, so a crafted mp4 file can no longer cause reads and\n       writes outside the allocated mp4 buffer\n     -
