Extended Description
It's a common idiom to have a fixed-size buffer of characters allocated on the stack and then to printf into the buffer. Create a check that recommends that the counted versions of functions are used, e.g. prefer snprintf over sprintf.
Example:
void f()
{
char buff[80];
sprintf(buff, "Hello, %s!\n", "world");
}
Becomes:
void f()
{
char buff[80];
snprintf(buff, sizeof(buff), "Hello, %s!\n", "world");
}
