+  <title>ed: Insecure temporary file handling</title>
+  <synopsis>
+    The ed utility is vulnerable to symlink attacks, potentially allowing a
+    local user to overwrite or change rights on arbitrary files with the rights
+    of the user running ed, which could be the root user.

+  <background>
+    <p>
+    ed is a line-oriented text editor, used to create or modify text files,
+    both interactively and via shell scripts.

+  <description>
+    <p>
+    ed insecurely creates temporary files in world-writeable directories with
+    predictable names. Given that ed is used in various system shell scripts,
+    they are by extension affected by the same vulnerability.
+    </p>
+  </description>
+  <impact type="normal">
+    <p>
+    A local attacker could create symbolic links in the temporary files
+    directory, pointing to a valid file somewhere on the filesystem. When ed is
+    called, this would result in file access with the rights of the user
+    running the utility, which could be the root user.
+    </p>
+  </impact>
+  <workaround>
+    <p>
+    There is no known workaround at this time.
+    </p>
+  </workaround>
+  <resolution>
+    <p>
+    All ed users should upgrade to the latest version:
+    </p>
