Here are the details from the Slackware 13.37 ChangeLog:
+--------------------------+
patches/packages/emacs-23.3-i486-2_slack13.37.txz: Rebuilt.
 Patched to fix a security flaw in the file-local variables code.
 When the Emacs user option `enable-local-variables' is set to `:safe'
 (the default value is t), Emacs should automatically refuse to evaluate
 `eval' forms in file-local variable sections. Due to the bug, Emacs
 instead automatically evaluates such `eval' forms. Thus, if the user
 changes the value of `enable-local-variables' to `:safe', visiting a
 malicious file can cause automatic execution of arbitrary Emacs Lisp
 code with the permissions of the user. Bug discovered by Paul Ling.
