----------------------------------
A] Endless loop in remote services
----------------------------------
All the NET-i ware services are affected by an endless loop caused by
the wrong handling of negative 32bit size fields.
----------------------------------------
B] Code execution in ConnectDDNS ActiveX
----------------------------------------
Code execution vulnerability in the ConnectDDNS method used by the
following ActiveX components:
- EEDBA32E-5C2D-48f1-A58E-0AAB0BC230E3
- 17A7F731-C9EC-461C-B813-2F42A1BB58EB
10022F80 8B02 MOV EAX,DWORD PTR DS:[EDX]
10022F82 8B4D E8 MOV ECX,DWORD PTR SS:[EBP-18]
10022F85 FF10 CALL DWORD PTR DS:[EAX]
The bug is not much reliable to replicate so I report it just for
reference.
No additional research performed.
----------------------------------------
C] Stack overflow in BackupToAvi ActiveX
----------------------------------------
Stack overflow in the BackupToAvi method used by the ActiveX components
3D6F2DBA-F4E5-40A6-8725-E99BC96CC23A and
208650B1-3CA1-4406-926D-45F2DBB9C299.
