Descriptions
Tencent RapidJSON is vulnerable to privilege escalation due to an integer underflow 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 underflow vulnerability (when the file is parsed), leading to elevation of privilege.
Tencent RapidJSON es vulnerable a la escalada de privilegios debido a un desbordamiento insuficiente de enteros en la función `GenericReader::ParseNumber()` de `include/rapidjson/reader.h` al analizar texto JSON de una secuencia. Un atacante debe enviar a la víctima un archivo manipulado que debe abrirse; esto desencadena la vulnerabilidad de desbordamiento de enteros (cuando se analiza el archivo), lo que lleva a la elevación de privilegios.
