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.

Security readout for executives and security teams

This old Bitcoin wallet encryption issue could leave previously unencrypted private keys recoverable inside wallet files. The risk matters only where wxBitcoin or bitcoind 0.4.x before 0.4.1, or 0.5.0rc, was used with wallet encryption. If exposed, the business impact is loss of control over associated Bitcoin funds. Exposure appears limited to legacy Bitcoin wallet files created or encrypted with wxBitcoin or bitcoind 0.4.x before 0.4.1, or 0.5.0rc. Current exposure depends on whether those wallet files still exist, held value, or were copied to untrusted systems. Prioritize investigation if the organization ever handled Bitcoin wallets with these 2011-era clients. For most modern environments, urgency is low unless legacy wallet files or backups remain in scope. Mitigation focus: Inventory legacy Bitcoin wallet files and clients from the affected versions.; Remove or upgrade vulnerable wxBitcoin and bitcoind versions.; Check original Bitcoin release guidance for version-specific remediation..
