+Subject: [PATCH 01/44] IJS device - try and secure the IJS server startup
+
+Bug #707051 ""ijs" device can execute arbitrary commands"
+
+The problem is that the 'IJS' device needs to start the IJS server, and
+that is indeed an arbitrary command line. There is (apparently) no way
+to validate it. Indeed, this is covered quite clearly in the comments
+at the start of the source:
+
+ * WARNING: The ijs server can be selected on the gs command line
+ * which is a security risk, since any program can be run.
+
+Previously this used the awful LockSafetyParams hackery, which we
+abandoned some time ago because it simply couldn't be made secure (it
+was implemented in PostScript and was therefore vulnerable to PostScript
+programs).
+
+This commit prevents PostScript programs switching to the IJS device
+after SAFER has been activated, and prevents changes to the IjsServer
+parameter after SAFER has been activated.
+
+SAFER is activated, unless explicitly disabled, before any user
+PostScript is executed which means that the device and the server
+invocation can only be configured on the command line. This does at
+least provide minimal security against malicious PostScript programs.
