Application crash via oversized character reference
Published Oct 27, 2024 · Updated Oct 30, 2024
Reachable assertion in TinyXML-2 10.0.0 and earlier allows attackers to crash a host application with a crafted XML document. XMLUtil::GetCharacterRef routes an oversized numeric character reference into TIXMLASSERT when its multiplier exceeds UINT_MAX, aborting assertion-enabled builds instead of rejecting the input. Exploitation requires a host application with assertions enabled to parse attacker-controlled XML; the resulting process exit interrupts that application without reading or modifying data.
