Multiple heap-based buffer overflows in the (1) abc_MIDI_drum and (2) abc_MIDI_gchord functions in load_abc.cpp in libmodplug 0.8.8.4 and earlier allow remote attackers to cause a denial of service (memory corruption and crash) and possibly execute arbitrary code via a crafted ABC.

Integer overflow in the abc_set_parts function in load_abc.cpp in libmodplug 0.8.8.4 and earlier allows remote attackers to cause a denial of service and possibly execute arbitrary code via a crafted P header in an ABC file, which triggers a heap-based buffer overflow.
