[Bug 1722364] Re: Invalid ADC commands sent via UDP will crash the app

 

AirDC++ now uses the regular dispatch function for parsing ADC UDP
commands that should fix the issue:
https://github.com/airdcpp/airgit/blob/6a40613788e7ed8a7478f4f1789bbd142a98d231/airdcpp/airdcpp/UDPServer.cpp#L130-L175

** Changed in: airdcpp
       Status: New => Fix Released

Title:
  Invalid ADC commands sent via UDP will crash the app

Status in AirDC++:
  Fix Released
Status in ApexDC++:
  New
Status in DC++:

Status in FlylinkDC++:

Bug description:
  The AdcCommand parsing function will throw ParseException on invalid
  commands:
  https://sourceforge.net/p/dcplusplus/code/ci/default/tree/dcpp/AdcCommand.cpp#l37

  However, SearchManager (UDPServer in AirDC++) won't catch those
  exceptions at all:
  https://sourceforge.net/p/dcplusplus/code/ci/default/tree/dcpp/SearchManager.cpp#l286

  
  As a result, you should be able to crash the app by sending the following raw text to the UDP port: 

  ARES T\n

  (I used https://packetsender.com for testing)
