ftp alg dos

The ftp alg dos tag covers a specific remote denial-of-service vulnerability in Open vSwitch, tracked as CVE-2026-34956, that affects userspace conntrack deployments when a malformed FTP EPASV command longer than 255 characters is processed by the FTP helper. While the bug resides in Open vSwitch rather than the Windows kernel, Microsoft's Security Update Guide entry gives Windows administrators a reason to care, especially in mixed estates, cloud fabrics, lab clusters, and container platforms. The tag highlights how a legacy protocol parser can still sit close enough to virtual network plumbing to interrupt modern workloads.
