- Summary
- Wasmtime 46.0.0 before 48.0.4 and 49.0.0 before 49.0.2 Host Panic via WASIp3 Timestamps
- Details
-
Wasmtime 46.0.0 before 48.0.4 and 49.0.0 before 49.0.2 contains a denial of service vulnerability in the wasmtime-wasi WASIp3 implementation that allows guests to abort the Unix host process. Guests with mutable preopened directory access can call set-times or set-times-at with negative seconds timestamps before the epoch, triggering an assertion failure that crashes the host.
