(RTMPDump: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in RTMPDump.
    The following is a list of vulnerabilities fixed:
      Additional decode input size checks
      Ignore zero-length packets
      Potential integer overflow in RTMPPacket_Alloc().
      Obsolete RTMPPacket_Free() call left over from original C++ to C
        rewrite
      AMFProp_GetObject must make sure the prop is actually an object
  
Impact :

    A remote attacker could entice a user to open a specially crafted media
      flash file using RTMPDump. This could possibly result in the execution of
      arbitrary code with the privileges of the process or a Denial of Service
      condition.
  
Workaround :

    There is no known workaround at this time."
