    • GroupWise 5.5 Enhancement Pack
    • GroupWise 5.5 Enhancement Pack SP1
    • GroupWise 5.5 Enhancement Pack SP2
    • GroupWise 5.5 Enhancement Pack SP3
    • GroupWise 6


Client and server versions of GroupWise 5.5 and prior, and GroupWise 6 SP1 are not vulnerable. Novell has released technical details regarding this vulnerability.

Impact

Any user on the system can read all emails on that system on an acount by account basis.
