Steamworks game clients/servers using P2P authentication vulnerable to denial of service
GHSA-g588-cjg3-6g78
- Affected
- crates.io steamworks < 0.13.1
- Fixed in
- 0.13.1· Vendor fix available
- Issue
- Processing the raw ValidateAuthTicketResponset callback data panics when the meAuthSessionResponse field is kEAuthSessionResponseAuthTicketNetworkIdentityFailure. This can lead to denial of service in game clients and servers using the beginauthenticationsession API to authenticate players if a malicious game client sends an authentication ticket with a network identity that does not match that of the verifier.
Recommended action: Upgrade to 0.13.1 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
