CVE-2026-110877— AdPlug through 2.4 Heap Out-of-Bounds Read via CdmoLoader::load

Quick assessment

Affected
adplug adplug
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

AdPlug 2.4 及之前版本中，src/dmo.cpp 文件里的 CdmoLoader::load() 函数存在堆溢出读取漏洞。攻击者可以通过提供一个被截断的 TwinTeam DMO 文件，从而在堆分配区域之外进行读取。攻击者可以构造一个 12 或 13 字节的 DMO 文件，经过 dmo_unpacker::decrypt() 函数处理，并通过 CAdPlug::factory 打开该文件，从而读取 packed_module 之后的内存数据，甚至可能导致应用程序崩溃。

Vulnerability Title
AdPlug through 2.4 Heap Out-of-Bounds Read via CdmoLoader::load
Source: CVE Program / CVE List V5
Vulnerability Description
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.
