NVD Description

Note: Versions mentioned in the description apply only to the upstream rust-wasmtime package and not the rust-wasmtime package as distributed by Debian. See How to fix? for Debian:14 relevant fixed versions and status.

Wasmtime before 36.0.17, 37.0.0 before 48.0.4, and 49.0.0 before 49.0.2 contains a denial of service vulnerability in the wasmtime-wasi WASI preview 0 poll_oneoff adapter, which performs O(n) host work per subscription without consuming or checking fuel. Malicious guest modules can pass many subscriptions to force long-running host computation that ignores configured fuel limits.
