Symptoms: A Cisco port adaptor CT3IP-50 running IOS version 12.0(32)S6 may reload
unexpectedly. This has been experienced many times. The information gathered points to a software
issue. This enclosure will be updated as more information is gathered.
CT3IP-50 w/ 128MB DRAM running 12.0.32.6 crashed due to:
%SYS-3-CPUHOG: Task ran for 123588 msec (2838/0), process = VIP Txacc loss compensation,
PC = 60308350. -Traceback= 60308358 : %SYS-2-WATCHDOG: Process aborted on watchdog

A vulnerability exists in the Data-link Switching (DLSw) feature in Cisco IOS where an invalid
value in a DLSw message could result in a reload of the DLSw device. Successful exploitation of
this vulnerability requires that an attacker be able to establish a DLSw connection to the device.
There are workarounds available for this vulnerability.

IP Routing Protocols
CSCek76776
Symptoms: The issue is observed at big service provider whereas atm-sub interfaces are deleted and
new one created on regular basis as they remove and add new end customers.
Because it is not a manual process as scripting is used to perform that task, old configuration from
deleted sub-interface are showing up on new sub-interfaces and in some cases are creating outages.
This issue was observed in version Cisco IOS Release 12.0(27)S5d.
Workaround: verify sub-interface configuration and if configuration cannot be deleted on that
sub-interface, delete this sub-interface then create a dummy sub-interface which will pull that
configuration. Then recreate prior sub-interface.
CSCin95836
The Cisco Next Hop Resolution Protocol (NHRP) feature in Cisco IOS contains a vulnerability that
can result in a restart of the device or possible remote code execution.
NHRP is a primary component of the Dynamic Multipoint Virtual Private Network (DMVPN)
feature.
