Improving Security on Cisco Routers http://www.cisco.com/warp/public/707/21.html
CSCec34459
Symptoms: A memory leak may occur in the "IP Input" process on a Cisco platform, and memory
allocation failures (MALLOCFAIL) may be reported in the processor pool.
Conditions: This symptom is observed on a Cisco platform that is configured for Network Address
Translation (NAT).
Workaround: There is no workaround.
CSCec51750
Symptoms: A router that is configured for HTTP and voice-based services may reload unexpectedly
because of an internal memory corruption.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.3 or
Release 12.3 T.
Workaround: There is no workaround. Note that the fix for this symptom prevents the router from
reloading and enables the router to generate the appropriate debug messages. The internal memory
corruption is addressed and documented in caveat CSCec20085.
CSCec72958
Symptoms: A Cisco router that is configured for Network Address Translation (NAT) may reload
unexpectedly because of a software condition.
Conditions: This symptom can occur when the router translates a Lightweight Directory Access
Protocol (LDAP) packet. NAT translates the embedded address inside the LDAP packet. This
problem is strictly tied to NAT and LDAP only.
Workaround: There is no workaround.
CSCee19691
Symptoms: A Cisco router may crash when you enter the clear ip route * command multiple times.
Conditions: This symptom is observed on a Cisco router that runs Cisco IOS Release 12.2S or
Release 12.3 and that is configured for RIP.
Workaround: There is no workaround.
CSCee30355
Symptoms: A Cisco router may experience a memory leak. The "Holding" column in the output of
the show process memory command shows that the "VTEMPLATE Backgr" process allocates
memory without freeing it. This column will continue to grow until all the memory is consumed.
Conditions: This symptom is observed on a Cisco router that is configured for RIP version 2. In
addition configuration with 800+ virtual-access interfaces using VPDN reported a memory leak for
the RIP multicast group.
Workaround: Schedule the router for a periodic reload before it completely exhausts all available
memory.
CSCef15846
Symptoms: There are two symptoms which are fixed by this bug.
