Description:
  While researching the previous xinetd problem (announced by zen-parse
  and discussed in Immunix OS Advisory IMNX-2001-70-024-01), Sebastian
  Krahmer found some improper handling of strings when the length
  argument to its own internal string handling functions is less than or
  equal to zero. We think this could lead to arbitrary code execution by
  remote attackers.

  Because the string handling functions are called with arguments both
  on the stack and on the heap, StackGuard is only partially effective
  at stopping possible attacks. As a result, we advise all Immunix OS
  7.0 users upgrade immediately.

  This advisory is released only for Immunix OS 7.0 because 6.2 used
  inetd. This advisory supercedes IMNX-2001-70-024-01.

  Thanks to Sebastian Krahmer for finding the problem and Rob Braun for
  fixing the problem upstream.
