Descriptions

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.

La característica "encrypt wallet" en wxBitcoin y en bitcoind v0.4.x y anteriores a v0.4.1, y v0.5.0rc no interactúa adecuadamente con la funcionalidad de eliminación de BSDDB, lo cual permite a atacantes dependiendo del contexto obtener claves privadas no encriptadas desde un fichero de monedero Bitcoin mediante el puenteo de la interfaz de BSDDB y a través de la lectura de entradas que han sido marcadas para su borrado.
