netword.c & fdprintf access access violation fix - stunnel-users

12 Sep 2011


      Hi, all
One more bug was found out at work stunnel through a proxy.
There is a reference to already released memory in fdprintf function.
Here a small fix of this situation:

  int fdprintf(CLI *c, int fd, const char *format, ...) {
      va_list ap;
      char *line;
+     int outsize;
va_start(ap, format);
      line=str_vprintf(format, ap);

          longjmp(c->err, 1);
      }
      fdputline(c, fd, line);
      str_free(line);
!     return strlen(line)+2;
  }
#define INET_SOCKET_PAIR
--- 776,784 ----
          longjmp(c->err, 1);
      }
      fdputline(c, fd, line);
+     outsize = strlen(line)+2;
      str_free(line);
!     return outsize;
  }
#define INET_SOCKET_PAIR
