CWE
- CWE-125 - Out-of-bounds Read
Summary
libmodplug through 0.8.9.1 contains a heap-based out-of-bounds read vulnerability in CSoundFile::ReadAMS2() in src/load_ams.cpp that allows attackers to read adjacent heap memory via crafted AMS files. Attackers can supply an AMS module whose pattern effect bytes keep bit 7 set, driving the decoder past the input buffer and crashing any libmodplug consumer.

- CWE-787 - Out-of-bounds Write
Summary
libmodplug through 0.8.9.1 contains a heap-based out-of-bounds write in CSoundFile::ReadDSM() in src/load_dsm.cpp because nPat is never checked against MAX_PATTERNS. Attackers can supply a crafted DSM file with over 240 PATT chunks or a wrapping patt_len value to corrupt heap memory and crash the consuming process.

CWE
- CWE-125 - Out-of-bounds Read
Summary
libmodplug through 0.8.9.1 contains an out-of-bounds read in pat_smplooped in src/load_pat.cpp. The function validates only the upper bound of its sample index against MAXSMP and then subtracts one before indexing the 191-byte static array pat_loops, so an index of zero reads pat_loops[-1], one byte before the array. The index is the smpno field of a parsed MIDI event, which is initialised to zero and only later overwritten from a program-change parameter, so an event reaching the note test before an instrument is assigned carries zero. A 32-byte MIDI file supplied to the library's public ModPlug_Load entry point drives the path through CSoundFile::Create, CSoundFile::ReadMID, and MID_ReadPatterns to the read. The byte read out of bounds determines whether a note event is treated as looping, so adjacent static storage influences playback state.
