S-242: Vulnerability in Cisco IOS with OSPF, MPLS VPN, and Supervisor 32, Supervisor

Cetrain Cisco Catalyst 6500 Series and Cisco 7600 Router devices that run branches of Cisco IOS based on 12.2 can be vulnerable to a denial of service vulnerability that can prevent any traffic from entering an affected interface. The risk is LOW. Exploitation of this vulnerability may result in a blocked interface input queue, memory leak, and/or restart of the device. Repeated exploitation of this vulnerability may result in an extended denial of service.

NAME
SNMP::Info::Layer2::Aironet - SNMP Interface to Cisco Aironet devices running IOS. AUTHOR
Max Baker SYNOPSIS
# Let SNMP::Info determine the correct subclass for you. my $aironet = new SNMP::Info( AutoSpecify => 1, Debug => 1, DestHost => 'myswitch', Community => 'public', Version => 2 ) or die "Can't connect to DestHost. "; my $class = $aironet->class(); print "SNMP::Info determined this device to fall under subclass : $class "; DESCRIPTION
Provides interface to SNMP Data available on newer Aironet devices running Cisco IOS. Note there are two classes for Aironet devices : SNMP::Info::Layer3::Aironet This class is for devices running Aironet software (older) SNMP::Info::Layer2::Aironet This class is for devices running Cisco IOS software (newer) For speed or debugging purposes you can call the subclass directly, but not after determining a more specific class using the method above. my $aironet = new SNMP::Info::Layer2::Aironet(...); Inherited Classes SNMP::Info::Layer2 SNMP::Info::Entity SNMP::Info::EtherLike SNMP::Info::CiscoStats SNMP::Info::CiscoConfig Required MIBs Inherited Classes MIBs required by the inherited classes listed above.

Overrides $aironet->interfaces() Uses the i_description() field. $aironet->i_mac() MAC address of the interface. Note this is just the MAC of the port, not anything connected to it. $aironet->i_duplex() Crosses information from SNMP::Info::EtherLike to get duplex info for interfaces. $aironet->bp_index() Returns reference to hash of bridge port table entries map back to interface identifier (iid) $aironet->fw_mac() Returns reference to hash of forwarding table MAC Addresses $aironet->fw_port() Returns reference to hash of forwarding table entries port interface identifier (iid) $aironet->i_vlan() Returns a mapping between "ifIndex" and the PVID or default VLAN. $aironet->v_index() Returns VLAN IDs $aironet->v_name() Returns VLAN names $aironet->i_ssidlist() Returns a list of SSIDs associated with interfaces. This function is "MBSSID" aware, so when using "MBSSID" can map SSIDs to the sub- interface to which they belong. $aironet->i_ssidbcast() With the same keys as i_ssidlist, returns whether the given SSID is being broadcast.
