Caveats
Resolved Caveats
These caveats are resolved in Cisco IOS Release 12.2(13)JA4:
•
CSCdz32659—Memory allocation failure (MALLOCFAIL) messages no longer occur for Cisco
Discovery Protocol (CDP) processes.
Discovery Protocol (CDP) processes.
•
CSCed27956—
A vulnerability in the Transmission Control Protocol (TCP) specification (RFC793) has been
discovered by an external researcher. The successful exploitation enables an adversary to reset any
established TCP connection in a much shorter time than was previously discussed publicly.
Depending on the application, the connection may get automatically re-established. In other cases,
a user will have to repeat the action (for example, open a new Telnet or SSH session). Depending
upon the attacked protocol, a successful attack may have additional consequences beyond
terminated connection which must be considered. This attack vector is only applicable to the
sessions which are terminating on a device (such as a router, switch, or computer) and not to the
sessions that are only passing through the device (for example, transit traffic that is being routed by
a router). In addition, this attack vector does not directly compromise data integrity or
confidentiality.
