Resolved Caveats—Cisco IOS Release 12.0(27)S4
Cisco IOS Release 12.0(27)S4 is a rebuild of Cisco IOS Release 12.0(27)S. The caveats listed in this
section are resolved in Cisco IOS Release 12.0(27)S4 but may be open in previous Cisco IOS releases.
This section describes only severity 1 and 2 caveats.
Basic System Services
• CSCdz61503
Symptoms: A Cisco router may reload when it performs Simple Network Management Protocol
(SNMP) Notification Log MIB queries.
Conditions: This symptom is observed on all versions of Cisco IOS software. The symptoms are not
observed on a Cisco ONS 15530 or a Cisco ONS 15540 switch module because the symptoms have
been resolved on these platforms.
Workaround: Exclude the NOTIFICATION-LOG-MIB.
• CSCec87661
Symptoms: A “SYS-2-CHUNKBOUNDS” error message may be displayed on the router console.
This message may be followed by a “NOTQ” error message.
Conditions: This symptom is observed under rare circumstances during heavy usage of any
application that is using chunks. The symptom is platform independent.
Workaround: There is no workaround.
• CSCed65285
Certain release trains of Cisco Internetwork Operating System (IOS), when configured to use the
Cisco IOS Secure Shell (SSH) server in combination with Terminal Access Controller Access
Control System Plus (TACACS+) as a means to perform remote management tasks on Cisco IOS
devices, may contain two vulnerabilities that can potentially cause Cisco IOS devices to exhaust
resources and reload. Repeated exploitation of these vulnerabilities can result in a Denial of Service
(DoS) condition. Use of SSH with Remote Authentication Dial-In User Service (RADIUS) is not
affected by these vulnerabilities.
Cisco has made free software available to address these vulnerabilities for all affected customers.
There are workarounds available to mitigate the effects of the vulnerability (see the “Workarounds”
section of the full advisory for details.)
This advisory will be posted at
http://www.cisco.com/warp/public/707/cisco-sa-20050406-ssh.shtml.
• CSCee87891
Symptoms: SNMP entries may be deleted when you configure SNMP or when you reload the router
on which SNMP is configured.
Conditions: This symptom is observed when an SNMP user is configured with the same name or
host name as a community.
Workaround: There is no workaround.
• CSCee95282
Symptoms: A router may generate a very large remote processing time report that may take between
10 and 25 seconds to be generated.
