Resolved Caveats

• CSCte14603

A vulnerability in the Internet Group Management Protocol (IGMP) version 3 implementation of

Cisco IOS Software and Cisco IOS XE Software allows a remote unauthenticated attacker to cause

a reload of an affected device. Repeated attempts to exploit this vulnerability could result in a

sustained denial of service (DoS) condition. Cisco has released free software updates that address

this vulnerability.

This advisory is posted at http://www.cisco.com/warp/public/707/cisco-sa-20100922-igmp.shtml.

Note: The September 22, 2010, Cisco IOS Software Security Advisory bundled publication includes

six Cisco Security Advisories. Five of the advisories address vulnerabilities in Cisco IOS Software,

and one advisory addresses vulnerabilities in Cisco Unified Communications Manager. Each

advisory lists the releases that correct the vulnerability or vulnerabilities detailed in the advisory.

After a software upgrade from Cisco IOS Release 12.2(52)SE to Cisco IOS Release 12.2(53)SE,

EIGRP hello packets are flooded on access ports belonging to another subnet. The same result

occurs when you initiate ping requests to the broadcast address of other subnets. This results in Not

on common subnet errors on the other side of the link.

The workaround is to downgrade to 12.2(52)SE

• CSCte94620

After you apply an ACL, these messages appear:

%IPACCESS-4-INVALIDACL: Invalid ACL field: Acl number is 0

%IPACCESS-4-INVALIDACL: Invalid ACL field: Acl type is 145

There is no workaround.

• CSCte99650

A Cisco Catalyst switch can report abnormal temperatures even though the output of the show

environment all user EXEC or privileged EXEC command shows that the temperatures are within

acceptable limits.

This is an example of the system messages:

Dec 25 19:03:57.463 AEST: %PLATFORM_ENV-1-TEMP: Abnormal temperature detected

Jan 2 04:04:46.600 AEST: %PLATFORM_ENV-1-TEMP: Abnormal temperature detected

Jan 7 06:33:36.067 AEST: %PLATFORM_ENV-1-TEMP: Abnormal temperature detected

This is an example of the output of the show environment all command:

Switch# show environment all

TEMPERATURE is OK

Temperature Value: 39 Degree Celsius

Temperature State: GREEN

Yellow Threshold : 80 Degree Celsius

Red Threshold : 90 Degree Celsius

There is no workaround.
