An exploitable denial-of-service vulnerability exists in the UDPRelay functionality of Shadowsocks-libev 3.3.2. When utilizing a Stream Cipher and a local_address, arbitrary UDP packets can cause a FATAL error code path and exit. An attacker can send arbitrary UDP packets to trigger this vulnerability.

In the following Java example the method createBankAccount is used to create a BankAccount object for a bank management application.
}
return account;However, there is no authentication mechanism to ensure that the user creating this bank account object has the authority to create new bank accounts. Some authentication mechanisms should be used to verify that the user has the authority to create bank account objects.
The following Java code includes a boolean variable and method for authenticating a user. If the user has not been authenticated then the createBankAccount will not create the bank account object.
}// authenticate user,// if user is authenticated then set variable to true// otherwise set variable to false...
return account;account.setBalance(balance);ExploitPedia is constantly evolving. Sign up to receive a notification when we release additional functionality.
