Backported from httpd\n       commit c721d4e1cf5c142149509490015cef1a75715595 (SVN r1935931).\n     - CVE-2026-56449\n   * SECURITY UPDATE: stack-based buffer overflow in mod_vhost_alias\n     - debian/patches/CVE-2026-63292.patch: in vhost_alias_checkspace()\n       and vhost_alias_interpolate() in modules/mappers/mod_vhost_alias.c,\n       reject a single expanded segment (e.g. a Host header) of\n       HUGE_STRING_LEN bytes or more with 414 instead of writing past the\n       stack buffer.
