Hi,

Sun classifies the issue discussed in Alert Notification #52465 ("Solaris 
System may Panic While Retransmitting a TCP Packet") as an 'Availability' 
issue.
http://sunsolve.sun.com/pub-cgi/retrieve.pl?doc=fsalert%2F52465

This is the description:
"A rare race condition may cause Solaris to panic while retransmitting a TCP 
packet. The retransmission is due to the original packet being delayed on 
the sending system instead of packet loss on the network."

I was wondering, firstly, what is exactly meant by 'the sending system'? Is 
this the same system that panics? The fact that this issue apparently occurs 
when 'REtransmitting' would suggest this, but I'm not sure I'm getting this 
right...
Secondly, if this situation can be triggered by a remote host, wouldn't this 
be a potential security issue? Does anyone have any evidence that this issue 
can indeed be triggered by a remote host?

Any info would be greatly appreciated.

Kind regards,

Lise
