Here is code in question:

  static char* OPT_parseOptFile(char *filename, char*validlist[])
  {
    FILE *fp;
    char buffer[1024];

    if (filename == NULL || filename[0] == '\0') {
       return ("Bad syntax for 'optfile'\n");
    }
    fp = fopen(filename,"r");              <---- line 79
    if (fp == NULL) {
       return ("Options file could not be opened for reading\n");
    }
    while (fgets(buffer,1024,fp)) {
       if (buffer[strlen(buffer)-1] == '\n') buffer[strlen(buffer)-1] = '\0';
       if (buffer[strlen(buffer)-1] == '\r') buffer[strlen(buffer)-1] = '\0';

       OPT_parseArgument(strdup(buffer),validlist);
    }
    fclose(fp);
    return NULL;
  }


1. NULL pointer returned from fopen is handled.
2. There is no existing file handle value that can be de-referenced by fopen.

This code is safe and I would like to qualify this case reported by Coverity as
  Classification: Intentional
          Action: Ignore

You are still going to leak cinfo on fopen() failure I am afraid.  But at least the crash should be fixed by this patch...

Did you want to call SEC_PKCS7DestroyContentInfo(cinfo) at this point?

I would also suggest to say "Couldn't open '%s' file for writing\n" in the error message to make the patch more user-friendly.

One caveat. Check this out first before finishing:
Block 275-285

 loser: 	

  errcode=14;	
  exitError(errbuf);	
  free(errbuf);

May be freeing something after the program is gone..
