CVE-2026-110877 (GCVE-0-2026-110877)

Vulnerability from nvd – Published: 2026-10-15 18:57 – Updated: 2026-10-15 19:56

Title

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

Summary

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.

CVE-2026-110876 (GCVE-0-2026-110876)

Vulnerability from nvd – Published: 2026-10-15 18:57 – Updated: 2026-10-15 18:57

Title

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

Summary

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.

Vulnerability from nvd – Published: 2026-10-15 18:57 – Updated: 2026-10-15 18:57

Title

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

Summary

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.

Vulnerability from cvelistv5 – Published: 2026-10-15 18:57 – Updated: 2026-10-15 19:56

Title

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

Summary

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.

CVE-2026-110876 (GCVE-0-2026-110876)

Vulnerability from cvelistv5 – Published: 2026-10-15 18:57 – Updated: 2026-10-15 18:57

Title

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

Summary

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.

Vulnerability from cvelistv5 – Published: 2026-10-15 18:57 – Updated: 2026-10-15 18:57

Title

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

Summary

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.
