Description
Cisco DSL CPE devices running CBOS 2.4.4 and earlier allows remote attackers to cause a denial of service (hang or memory consumption) via (1) a large packet to the DHCP port, (2) a large packet to the Telnet port, or (3) a flood of large packets to the CPE, which causes the TCP/IP stack to consume large amounts of memory.

Comments (Legacy)
Jones> A single large packet DoS to a listening service (which sounds like a buffer overflow) seems like a different vulnerability than multiple large packets (which is admittedly resource consumption). Suggest SPLIT into two items, prolems 1 and 2 in A, and problem 3 in B.
