Original description

The description as published by the source.

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.
