    A buffer overflow can be triggered within xdelta when ran against a

Impact :

    A remote attacker could coerce the victim to run xdelta against a
      malicious input file. This may be leveraged by an attacker to crash
      xdelta and gain control of program execution.
  
Workaround :

    There is no known workaround at this time."
