+	<blockquote cite="https://go.dev/issue/56694">
+	  <p>os, net/http: avoid escapes from os.DirFS and http.Dir on Windows</p>
+	  <p>The os.DirFS function and http.Dir type provide access to a
+	   tree of files rooted at a given directory. These functions
+	   permitted access to Windows device files under that root. For
+	   example, os.DirFS("C:/tmp").Open("COM1") would open the COM1 device.
+	   Both os.DirFS and http.Dir only provide read-only filesystem access.</p>
+	  <p>In addition, on Windows, an os.DirFS for the directory \(the root
+	   of the current drive) can permit a maliciously crafted path to escape
+	   from the drive and access any path on the system.</p>
+	  <p>The behavior of os.DirFS("") has changed. Previously, an empty root
+	   was treated equivalently to "/", so os.DirFS("").Open("tmp") would
+	   open the path "/tmp". This now returns an error.</p>
+	</blockquote>
+	<blockquote cite="https://go.dev/issue/56350">
+	  <p>net/http: limit canonical header cache by bytes, not entries</p>
+	  <p>An attacker can cause excessive memory growth in a Go server
+	    accepting HTTP/2 requests. HTTP/2 server connections contain a
+	    cache of HTTP header keys sent by the client. While the total number
+	    of entries in this cache is capped, an attacker sending very large
+	    keys can cause the server to allocate approximately 64 MiB per open
+	    connection.</p>
