      negative value on numbers of bytes read from the diff and extra streams.
  
Impact :

    A remote attacker could entice a user to apply a specially crafted patch
      using bspatch, possibly resulting in execution of arbitrary code with the
      privileges of the process or a Denial of Service condition.
  
Workaround :

"The implementation of bspatch does not check for a negative value on
numbers of bytes read from the diff and extra streams, allowing an
attacker who can control the patch file to write at arbitrary
locations in the heap.

This issue was first discovered by The Chromium Project and reported
independently by Lu Tung-Pin to the FreeBSD project. Impact : An
attacker who can control the patch file can cause a crash or run
arbitrary code under the credentials of the user who runs bspatch, in
many cases, root."
