(GNU Emacs: Multiple vulnerabilities)

    Drake Wilson reported that the hack-local-variables() function in GNU
    Emacs 22 does not properly match assignments of local variables in a
    file against a list of unsafe or risky variables, allowing to override
    them (CVE-2007-5795). Andreas Schwab (SUSE) discovered a stack-based
    buffer overflow in the format function when handling values with high
    precision (CVE-2007-6109).
  
Impact :

    Remote attackers could entice a user to open a specially crafted file
    in GNU Emacs, possibly leading to the execution of arbitrary Emacs Lisp
    code (via CVE-2007-5795) or arbitrary code (via CVE-2007-6109) with the
    privileges of the user running GNU Emacs.
  
Workaround :

    The first vulnerability can be worked around by setting the
    'enable-local-variables' option to 'nil', disabling the processing of
    local variable lists. GNU Emacs prior to version 22 is not affected by
    this vulnerability. There is no known workaround for the second
    vulnerability at this time."
