I have a contract A calling another contract B
Contract A
contract A
function sendValue(B _externalContract, uint _value)
_externalContract.acceptValue(_value);
contract B
function acceptValue(unit value);
Contract B (contract A expect contract B acceptValue to be safe)
contract B
function acceptValue(unit _value)
dosomethingWith(_value)
If a malicious user now design contract B function acceptValue to self destruct like so
Contract B
contract B
function acceptValue(unit _value)
selfdestruct(msg.sender);
- Will that function destroy my contract A or malicious user Contract B?
- Is there a check I can perform in contract A
sendValueto prevent that?

It destroys Contract B and sends B's Eth balance to contract A, if called from A.
There is no way B can destroy A. Otherwise, there would be chaos.
Hope it helps.
