  "details" : [ "NGINX Plus and NGINX Open Source have a vulnerability in the ngx_http_slice_module module. When the slice directive and unnamed regex captures are configured or when a background cache update happens, unauthenticated attackers can send requests that may cause uninitialized memory access in the NGINX worker process, leading to limited disclosure of memory or a restart.\nImpact:\nThis vulnerability may allow remote, unauthenticated attackers to have limited control to disclose memory contents or restart the NGINX worker process. There is no control plane exposure; this is a data plane issue only.\nNote: The ngx_http_slice_module module is not enabled by default; it's enabled with the --with-http_slice_module configuration parameter.\nNote: Software versions which have reached End of Technical Support (EoTS) are not evaluated.", "A vulnerability in the NGINX ngx_http_slice_module allows remote, unauthenticated attackers to access uninitialized memory via crafted requests. If configured with unnamed regex captures or background cache updates, this flaw can result in limited memory disclosure or a denial-of-service crash." ],
  "statement" : "Important: This vulnerability in NGINX's `ngx_http_slice_module` could lead to memory disclosure or denial of service. The impact on Red Hat products is reduced because the `ngx_http_slice_module` is not enabled by default. Exploitation requires explicit configuration of the module with the `slice` directive and unnamed regex captures, or during a background cache update, limiting exposure in typical deployments.",
