Description

The \encrypt wallet\ feature in wxBitcoin and bitcoind 0.4.x before 0.4.1 and 0.5.0rc does not properly interact with the deletion functionality of BSDDB which allows context-dependent attackers to obtain unencrypted private keys from Bitcoin wallet files by bypassing the BSDDB interface and reading entries that are marked for deletion.
