DescriptionCVE.org

Tencent RapidJSON is vulnerable to privilege escalation due to an integer overflow in the GenericReader::ParseNumber() function of include/rapidjson/reader.h when parsing JSON text from a stream. An attacker needs to send the victim a crafted file which needs to be opened; this triggers the integer overflow vulnerability (when the file is parsed), leading to elevation of privilege.
