improper use of internal data structures. This enhancement was introduced in select Cisco IOS
software releases published after April 5, 2007.
Details: With the new enhancement in place, Cisco IOS software will emit a
“%DATACORRUPTION-1-DATAINCONSISTENCY” error message when it detects an
inconsistency in its internal data structures. This is a new error message. The following is an
example.

inconsistency in its internal data structures. This is a new error message. The following is an
example.
The %DATACORRUPTION-1-DATAINCONSISTENCY error message is preceded by a timestamp
May 17 10:01:27.815 UTC: %DATACORRUPTION-1-DATAINCONSISTENCY: copy error
The error message is then followed by a traceback.
It is important to note that this error message does not imply that packet data is being corrupted. It
does, however, provide an early indicator of other conditions that can eventually lead to poor system
performance or an IOS restart.

A vulnerability exists in the Data-link Switching (DLSw) feature in Cisco IOS where an invalid
value in a DLSw message could result in a reload of the DLSw device. Successful exploitation of
this vulnerability requires that an attacker be able to establish a DLSw connection to the device.
