(Apache: Off-by-one flaw in mod_rewrite)

    An off-by-one flaw has been found in Apache's mod_rewrite module by
    Mark Dowd of McAfee Avert Labs. This flaw is exploitable depending on
    the types of rewrite rules being used.
  
Impact :

    A remote attacker could exploit the flaw to cause a Denial of Service
    or execution of arbitrary code. Note that Gentoo Linux is not
    vulnerable in the default configuration.
  
Workaround :

    There is no known workaround at this time."
