Cisco Cisco Aironet 1310 Access Point Bridge Notas de publicación

CSCeh06200—With TACACS configured, administrators can now log into the access point GUI 
when idle time is configured on the TACACS server.

CSCeh08952—Access points now correctly filter traffic through the TCP port when an IP filter is 
configured.

CSCsa40042, CSCsa40045—The user interfaces on the access point/bridge no longer allow you to 
configure the bridge to fall back to repeater mode. 

CSCsa40861—Access points configured for a fallback role now assume the fallback role if the LAN 
interface is down when they reboot.

CSCsa52462—Access points configured for CKIP or CMIC now indicate CKIP and CMIC support 
in beacons.

CSCsa59600—A document that describes how the Internet Control Message Protocol (ICMP) could 
be used to perform a number of Denial of Service (DoS) attacks against the Transmission Control 
Protocol (TCP) has been made publicly available. This document has been published through the 
Internet Engineering Task Force (IETF) Internet Draft process, and is entitled “ICMP Attacks 
Against TCP” (draft-gont-tcpm-icmp-attacks-03.txt).

These attacks, which only affect sessions terminating or originating on a device itself, can be of 
three types:

1. Attacks that use ICMP “hard” error messages. 2. Attacks that use ICMP “fragmentation needed 
and Don’t Fragment (DF) bit set” messages, also known as Path Maximum Transmission Unit 
Discovery (PMTUD) attacks. 3. Attacks that use ICMP “source quench” messages.

Successful attacks may cause connection resets or reduction of throughput in existing connections, 
depending on the attack type.

Multiple Cisco products are affected by the attacks described in this Internet draft.

Cisco has made free software available to address these vulnerabilities. In some cases there are 
workarounds available to mitigate the effects of the vulnerability.

.

The disclosure of these vulnerabilities is being coordinated by the National Infrastructure Security 
Coordination Centre (NISCC), based in the United Kingdom. NISCC is working with multiple 
vendors whose products are potentially affected. Its posting can be found at 

CSCsa61263—Client devices assigned to a non-native VLAN and connected to a workgroup bridge 
no longer lose their network connection when the workgroup bridge roams from one root device to 
another.

CSCsa64627—STP now functions properly when the native VLAN is not VLAN 1.
