The packet-reassembly implementation in Cisco IOS XE 3.13S and previous versions allows remote malicious users to cause a denial of service (CPU consumption or packet loss) via fragmented (1) IPv4 or (2) IPv6 packets that trigger ATTN-3-SYNC_TIMEOUT errors after reassembly failures, aka Bug ID CSCuo37957.
