DESCRIPTION:
A weakness and two vulnerabilities have been reported in IBM Lotus
Mobile Connect, which can be exploited by malicious people with
physical access to bypass certain security restrictions and malicious
people to cause a DoS (Denial of Service)

1) The weakness is caused due to the Connection Manager not properly
deleting the LTPA token for a session after the user logs off via the
"Logoff" button, which can be exploited to bypass the authentication.

Successful exploitation requires that the attacker has e.g. access to
an unattended client.

2) The Connection Manager does not properly handle failed connection
attempts to the HTTP-TCP based Mobile Network Connections (MNC),
which can be exploited to e.g. cause an out-of-memory condition,
resulting in a crash.

3) An error exists within the reference counter of the Connection
Manager when handling repeated logons with the same VPN ID, which can
be exploited to desynchronise the reference counter of active
sessions, leading to an exhaustion of e.g. all available dynamic IP
addresses.

SOLUTION:
Contact the IBM Lotus Mobile Connect Support Center to receive
temporary fixes. Reportedly, versions after 6.1.4 will contain the
fixes.
