Description

The squeue_drain function in Sun Solaris 10, possibly only when run on CMT processors, allows remote attackers to cause a denial of service ("bad trap" and system panic) by opening and closing a large number of TCP connections ("heavy TCP/IP loads"). NOTE: the original report specifies the function name as "drain_squeue," but this is likely incorrect.
