Vulnerability from variot
Cisco IOS XE does not properly manage memory for TFTP UDP flows, which allows remote attackers to cause a denial of service (memory consumption) via TFTP (1) client or (2) server traffic, aka Bug IDs CSCuh09324 and CSCty42686. Cisco IOS is the interconnected network operating system used on most Cisco system routers and network switches. A denial of service vulnerability exists in Cisco IOS XE Software. An attacker can exploit the vulnerability to consume excess memory and cause the device to crash, denying service to legitimate users. This issue is being tracked by Cisco Bug ID CSCuh09324 and CSCty42686. The vulnerability is caused by the program not properly freeing memory
