MAJOR BUG FIX (CVE-2011-4447)
The wallet encryption feature introduced in Palladium version 0.4.0 did not sufficiently secure the private keys. An attacker who managed to get a copy of your encrypted wallet.dat file might be able to recover some or all of the unencrypted keys and steal the associated coins.
If you have a previously encrypted wallet.dat, the first time you run wxpalladium or palladiumd the wallet will be rewritten, Palladium will shut down, and you will be prompted to restart it to run with the new, properly encrypted file.
If you had a previously encrypted wallet.dat that might have been copied or stolen (for example, you backed it up to a public location) you should send all of your palladiums to yourself using a new palladium address and stop using any previously generated addresses.
Wallets encrypted with this version of Palladium are written properly.
Technical note: the encrypted wallet's 'keypool' will be regenerated the first time you request a new palladium address; to be certain that the new private keys are properly backed up you should:
-
Run Palladium and let it rewrite the wallet.dat file
-
Run it again, then ask it for a new palladium address. wxPalladium: new address visible on main window palladiumd: run the 'walletpassphrase' RPC command to unlock the wallet, then run the 'getnewaddress' RPC command.
-
If your encrypted wallet.dat may have been copied or stolen, send all of your palladiums to the new palladium address.
-
Shut down Palladium, then backup the wallet.dat file. IMPORTANT: be sure to request a new palladium address before backing up, so that the 'keypool' is regenerated and backed up.
"Security in depth" is always a good idea, so choosing a secure location for the backup and/or encrypting the backup before uploading it is recommended. And as in previous releases, if your machine is infected by malware there are several ways an attacker might steal your palladiums.
