Event type spoofing via UntrustedType in github.com/google/go-eventlog
- Affected
- Go github.com/google/go-eventlog < 0.0.3-0.20261001001437-1991f15bc4b0
- Fixed in
- 0.0.3-0.20261001001437-1991f15bc4b0· Vendor fix available
- Issue
- In github.com/google/go-eventlog/tcg, Event exposes UntrustedType, which returns the raw event type header from the TCG event log without verifying that the event data matches its digest. Callers that dispatch on Event.UntrustedType after ParseAndReplay can be tricked by a modified event type field for events whose digests are not verified against EventData.
Recommended action: Upgrade to 0.0.3-0.20261001001437-1991f15bc4b0 (pre-release) or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
