the USN-4831-1 advisory.

  - soundlib/Snd_fx.cpp in OpenMPT before 1.27.07.00 and libopenmpt before 0.3.8 allows remote attackers to
    cause a denial of service (out-of-bounds read) via an IT or MO3 file with many nested pattern loops.
    (CVE-2018-10017)

  - soundlib/pattern.h in libopenmpt before 0.3.9 allows remote attackers to cause a denial of service
    (application crash) or possibly have unspecified other impact via a crafted AMS file because of an invalid
    write near address 0 in an out-of-memory situation. (CVE-2018-11710)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
