Missing fixes (this build is still exposed)

Security

Server crashes from malformed connection, HTTP and latent-event input

Missing bounds checks in the connection handshake, the HTTP request parser and latent event reassembly could crash the server when it received crafted data. Anyone who can reach the server's port could trigger it. Update to 38435 or newer.

Fixed in 384357892692
Security

One client could freeze the server by flooding game events

Before 37262 there was no core rate limit on netGameEvent packets. A single client could flood events such as weaponDamageEvent until the main thread hung and txAdmin restarted the server. The issue was reported on 35636 and 36727. 37262 drops clients that go over the new 'netGameEvent' rate limiter.

Security

Latent event reassembly is now bounded

The server's reassembly of large client-to-server latent events got hard limits, plus diagnostics for 'latent ACK overflow'. Older builds let a client keep more partial event state than they needed to, which costs memory and CPU.

Security

Better rate limiting for client latent events

Rate limiting of latent (TriggerLatentServerEvent) traffic from clients was tightened in the reassembly packet handler. On older builds a client could push latent event traffic harder than intended.

Security

Clients can no longer create multiple player objects

With OneSync, a modified client could register more than one networked player object (CNetObjPlayer) for itself. That is a known abuse path for desync and crashes. Since 23984 the server rejects the extra ones.

Security

New block_net_game_event command

Server owners can now block specific net game event types from clients with block_net_game_event (and undo it with unblock_net_game_event). Use it when an event type is being abused. The syntax was simplified in 16541.

Security

sv_protectServerEntities: stop clients deleting server-created entities

This new replicated convar (default off) protects entities created by server scripts from being deleted by clients. If cheaters delete your server-spawned vehicles, peds or props, run 14317 or newer and set sv_protectServerEntities true.

Fixed in 14317d6842fe
Security

Synchronized scenes on other players' entities are sanitized

The server now checks network synchronized scenes started by a client on entities that client does not own, a common way to force animations on other players. 13174 also adds SET/GET_ENTITY_REMOTE_SYNCED_SCENES_ALLOWED to control this per entity.

Fixed in 131747be0199
Security

State bag strict mode (sv_stateBagStrictMode)

With setr sv_stateBagStrictMode true, clients can no longer change replicated state bags at all. Only the server can write them. Turn it on if your scripts never need client-written state bags, because cheaters commonly abuse them.

Fixed in 127394994377
Voice

voip-server-mumble crash from empty voice messages

The server accepted empty Mumble messages from clients, which could crash FXServer in voip-server-mumble (GitHub #3054, reported on 12180). Since 12906 a message must carry at least one byte.

Fixed in 12906Affected 121802974200#3054
Voice

Mumble server network robustness

Oversized or invalid outgoing voice messages used to hit an assertion. They are now dropped cleanly, and the send queue is drained properly. The voice server should be less likely to stall or crash under bad traffic.
