+	  <p>
+	    GNU Emacs through 28.2 allows attackers to execute
+	    commands via shell metacharacters in the name of a
+	    source-code file, because lib-src/etags.c uses the system
+	    C library function in its implementation of the ctags
+	    program. For example, a victim may use the "ctags *"
+	    command (suggested in the ctags documentation) in a
+	    situation where the current working directory has contents
+	    that depend on untrusted input.
