Microsoft Outlook plug-in PGP version 7.0, 7.0.3, and 7.0.4 silently saves a decrypted copy of a message to hard disk when "Automatically decrypt/verify when opening messages" option is checked, "Always use Secure Viewer when decrypting" option is not checked, and the user replies to an encrypted message.

Network Associates PGP 7.0.4 and 7.1 does not time out according to the value set in the "Passphrase Cache" option, which could allow attackers to open encrypted files without providing a passphrase.
