An interaction between PGP 7.0.3 with the wipe deleted files option, when used on Windows Encrypted File System (EFS), creates a cleartext temporary files that cannot be wiped or deleted due to strong permissions, which could allow certain local users or attackers with physical access to obtain cleartext information.
Weakness
The product does not properly “clean up” and remove temporary or supporting resources after they have been used.
