Changes

  1. Change foundin to "1.0.11"
  2. Change icomment to:

    The udpOpen function has two problems when reporting errors. The first is a simple typo:

    char errmsg[] = "upd_open [remoteport] [ipv6] [reuse]";

    It should read "udp_open".

    The second problem is more serious. The call to Tcl_SetResult is:

    Tcl_SetResult (interp, errmsg, NULL);

    The last argument should read TCL_VOLATILE, since the error string is allocated on the stack. The value of NULL is equivalent to TCL_STATIC. This could cause a segmentation fault.

    The udpConf function also contains a call to Tcl_SetResult with a NULL argument.

  3. Change login to "anonymous"
  4. Change mimetype to "text/x-fossil-plain"
  5. Change private_contact to "1c57e67924247fd7926e89348f266c081ec57db2"
  6. Change severity to "Severe"
  7. Change status to "Open"
  8. Change title to "udp_open and udp_conf error reporting"
  9. Change type to "Code_Defect"
