VAR-201504-0289

Vulnerability from variot - Updated: 2025-04-12 23:28

The Overlay Transport Virtualization (OTV) implementation in Cisco IOS XE 3.10S allows remote attackers to cause a denial of service (device reload) via a series of packets that are considered oversized and trigger improper fragmentation handling, aka Bug IDs CSCup37676 and CSCup30335. Cisco IOS XE is an operating system developed by Cisco Systems for its network devices. A remote attacker could exploit the vulnerability to cause a denial of service (device reload). This issue is being tracked by Cisco Bug ID's CSCup37676 and CSCup30335
