Description
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.
