Potential security issue in src/tool_paramhlp.c: Unchecked return from initialization function

[monocle-ai]

What is a Conditionally Uninitialized Variable? The return value of a function that is potentially used to initialize a local variable is not checked. Therefore, reading the local variable may result in undefined behavior.

1 instance of this defect were found in the following locations:

Instance 1
File : src/tool_paramhlp.c
Function: strtol

curl/src/tool_paramhlp.c

Line 186 in 17b1405

num = strtol(str, &endptr, 10);

Code extract:

    char *endptr;
    long num;
    errno = 0;
    num = strtol(str, &endptr, 10); <------ HERE
    if(errno == ERANGE)
      return PARAM_NUMBER_TOO_LARGE;
