AdPlug through 2.4 Heap Buffer Overflow via CksmPlayer::update in ksm.cpp

AdPlug through 2.4 contains a heap-based buffer overflow in CksmPlayer::update() in src/ksm.cpp that writes past the fixed databuf[2048] array without bounds checking. Attackers can supply a crafted .ksm module whose notes share one time slot to overflow the heap player object, causing memory corruption and denial of service.

AdPlug through 2.4 Out-of-Bounds Read via CxsmPlayer::play_note in XSM Files

AdPlug through 2.4 contains an out-of-bounds read vulnerability in src/xsm.cpp that allows attackers to read before note_table by supplying a negative note index. Attackers can craft an XSM file with the ofTAZ! signature and a song byte of 0x80 or higher, causing a global-buffer-overflow read during playback that may crash affected applications.

AdPlug through 2.4 Heap Out-of-Bounds Read via CdmoLoader::load

AdPlug through 2.4 contains a heap out-of-bounds read vulnerability in CdmoLoader::load() in src/dmo.cpp that allows attackers to read past a heap allocation by supplying a truncated TwinTeam DMO file. Attackers can supply a 12- or 13-byte file passing dmo_unpacker::decrypt(), opened via CAdPlug::factory, to read bytes beyond packed_module and potentially crash the application.

AdPlug 2.3.1 has a double free in the Cu6mPlayer class in u6m.h.

AdPlug 2.3.1 has multiple heap-based buffer overflows in CmtkLoader::load() in mtk.cpp.

AdPlug 2.3.1 has multiple heap-based buffer overflows in CradLoader::load() in rad.cpp.

AdPlug 2.3.1 has multiple heap-based buffer overflows in Ca2mLoader::load() in a2m.cpp.

AdPlug 2.3.1 has a heap-based buffer overflow in CmkjPlayer::load() in mkj.cpp.

AdPlug 2.3.1 has a heap-based buffer overflow in CdtmLoader::load() in dtm.cpp.

AdPlug 2.3.1 has a heap-based buffer overflow in CxadbmfPlayer::__bmf_convert_stream() in bmf.cpp.

An issue was discovered in AdPlug 2.3.1. There are several double-free vulnerabilities in the CEmuopl class in emuopl.cpp because of a destructor's two OPLDestroy calls, each of which frees TL_TABLE, SIN_TABLE, AMS_TABLE, and VIB_TABLE.
