Bug 2315

Summary: Array w going out of boundary in read_config_file function
Product: SDL_mixer Reporter: Nitz <nitin.j4>
Component: miscAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED DUPLICATE QA Contact: Sam Lantinga <slouken>

Description Nitz 2013-12-18 09:09:58 UTC 
In static int read_config_file(const char *name) function array going out of boundary at :

while (w[words] && (words < MAXWORDS))
      {
        w[++words]=strtok(0," \t\r\n\240");
        if (w[words] && w[words][0]=='#') break;
      }
here w[++words] will go out of boundary when words = MAXWORDS
So to avoid this, fix should be:

while (w[words] && (++words < MAXWORDS))
      {
        w[words]=strtok(0," \t\r\n\240");
        if (w[words] && w[words][0]=='#') break;
      }

Thanks...
