The following items are resolved in Release 4.1.5
Line Cards
DDTS # CSCed06531
Malformed IP packets can potentially cause the XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards
to reset. Repeated transmission of these malformed packets could cause both the control cards to reset
at the same time. This issue is resolved in Release 5.0, and maintenance Releases 4.1.4, 2.3.5, 4.0.3, and
4.6.2.

The XTC, TCC/TCC+/TCC2 and TCCi/TCC2 control cards are susceptible to a TCP-ACK Denial of
Service (DoS) attack on open TCP ports. The controller card on the optical device will reset under such
an attack.
Service (DoS) attack on open TCP ports. The controller card on the optical device will reset under such
an attack.
A TCP-ACK DoS attack is conducted by withholding the required final ACK (acknowledgement) for a
3-way TCP handshake to complete, and instead sending an invalid response to move the connection to
an invalid TCP state. This issue is resolved in maintenance Releases 4.1.4, 2.3.5, 4.0.3, and 4.6.2.
