CTR50-CPP: Failed to compute the proper range for a resized vector. #66
Description
Affected rules
- cpp/cert/container-access-without-range-check-cert
Description
The rule warns about the vector container which is resized after delectation.
Access of container of type Payload does not ensure that the index is smaller than the bounds.
Example
#include <iostream>
#include <string>
#include <vector>
#include <filesystem>
using namespace std;
namespace fs = std::filesystem;
int main() {
typedef vector<uint8_t> Payload;
wstring file(L"This is a wstring");
uint64_t attributes;
Payload serialized_data; serialized_data.resize(file.size() * sizeof(wchar_t) + sizeof(attributes));
*(uint64_t*)&serialized_data.front() = attributes;
/*
* Append the path.
*/
file.copy((wchar_t*)&serialized_data[sizeof(attributes)], file.size());
return 0;
}
