In de updates zijn 3 kwetsbaarheden verholpen:    <\/p>\n<ul>\n<li class=\"l\"> CVE-2026-42533 \u2014 buffer overflow that occurs when using the 'map' directive with regular expression checks utilizing unnamed (e.g., $1 and $2) or named variables, provided that those variables are referenced before the map result variable or a variable that is not cached is used. This vulnerability could potentially lead to remote code execution on <a class=\"wpil_keyword_link\" href=\"https:\/\/prohoster.info\/nl\/server\/dts-dronten\/\" title=\"de server\" data-wpil-keyword-link=\"linked\">de server<\/a> door het verzenden van een speciaal opgemaakte HTTP-aanroep. De kwestie is geclassificeerd als kritisch (9,2 van 10).\n<li class=\"l\"> CVE-2026-60005 \u2014 uninitialized memory leakage of the worker process when using the ngx_http_slice_module and specifying regular expressions with unnamed variables in the slice directive. The vulnerability has been assigned a severity level of 8.8 out of 10.\n<li class=\"l\"> CVE-2026-56434 \u2014 access to memory after it has been freed in the ngx_http_ssi_module, occurring when processing a specially crafted response returned from a proxied backend. This vulnerability could lead to modification of the memory content of the worker process. The issue has been assigned a severity level of 8.3 out of 10.        <\/ul>\n<p>Wijzigingen die niet gerelateerd zijn aan kwetsbaarheden:  <\/p>\n<ul>\n<li class=\"l\">  In the ngx_http_xslt_filter_module, the loading of variables in the XML document, whose values are loaded from external sources, has been disabled. An 'xml_external_entities' directive has been added to control the loading of external components specified in the DTD block of the processed XML document.\n<li class=\"l\"> New directives 'proxy_socket_sndbuf', 'proxy_socket_rcvbuf', 'fastcgi_socket_sndbuf', 'fastcgi_socket_rcvbuf', 'grpc_socket_sndbuf', 'grpc_socket_rcvbuf', 'scgi_socket_sndbuf', 'scgi_socket_rcvbuf', 'uwsgi_socket_sndbuf', 'uwsgi_socket_rcvbuf', 'tunnel_socket_sndbuf', and 'tunnel_socket_rcvbuf' have been added to set the send (SO_SNDBUF) and receive (SO_RCVBUF) buffer sizes.\n<li class=\"l\"> Voor de LoongArch64-architectuur is de blokgrootte (cache line) ge\u00efmplementeerd, die wordt gebruikt voor de gegevensoverdracht tussen de CPU-cache en het geheugen.\n<li class=\"l\"> In de ngx_http_proxy_v2_module en ngx_http_grpc_module is een limiet voor de grootte van de headers en trailers in HTTP\/2-antwoorden ge\u00efmplementeerd met behulp van de richtlijnen proxy_buffer_size en
