Code Red -> Router Memory depletion?

  • From: Mike Lewinski
  • Date: Thu Jul 19 15:02:58 2001

We've seen two routers experiencing problems this AM that appear to be
related to client swervers infected with the IIS Code Red virus. I say
appear because of the timing with cpu profiles on downstream routers
where infections broke out, but I don't have any direct evidence.

The first one was a border router:

Jul 19 08:00:47 5093: 2w5d: %SYS-2-MALLOCFAIL: Memory allocation of
65540 bytes failed from 0x603BF35C, pool Processor, alignment 0
Jul 19 08:00:47 5094: -Process= "BGP Router", ipl= 0, pid= 86

# sh ver
uptime is 4 hours, 46 minutes
System returned to ROM by bus error at PC 0x603BFCFC, address 0xFFFFFFF0
at 05:57:21 UTC Thu Jul 19 2001

The other one is a client aggregation router

Jul 19 12:02:49 192: %SYS-2-MALLOCFAIL: Memory allocation of 1964 bytes
failed from 0x314DA4A, pool Processor, alignment 0
Jul 19 12:02:49 193: -Process= "OSPF Router", ipl= 0, pid= 32

(This router is still functioning, but not allowing any incoming
connections on telnet).
