Summary
Klei Entertainment's Don't Starve Together through build 747465 contains an out-of-bounds write (CWE-787) in its native persistent-string decoder. A remote attacker running a public dedicated server can publish crafted world_gen_data with an invalid Klei persistent blob header length. When the victim views or selects the attacker's server listing, the client decodes the attacker-controlled data, corrupts native memory and crashes, causing a remote denial of service.

Description from the CNA
Don't Starve Together (Steam AppID 322330) through build 747465 contains a memory-corruption vulnerability in the native persistent-string decoder that allows a remote attacker operating a public dedicated server to crash a victim's game client by publishing crafted world_gen_data with an invalid Klei persistent blob header length. Attackers can craft a malicious public lobby server listing that, once viewed or selected by the victim, triggers client-side decoding of the attacker-controlled data to corrupt native memory and cause a remote denial of service.
