I’ll keep updating/editing/correcting this page as I go along. The attack hinges on a specific flaw in the packet reassembly mechanism (CVE-2020-6016) and a quirk in C++'s implementation of iterators to send a bunch of malicious packets to a target game server and trigger a heap-based buffer underflow, ultimately causing the server to abort or crash.įollowing responsible disclosure to Valve on September 2, 2020, the binary updates containing the fixes were shipped to Valve's game clients and servers on September 17.īut according to Check Point, certain third-party game developers are yet to patch their clients as of December 2.Just some personal notes for me setting up my Dell PowerEdge 1950 as a Steam-pipe Day of Defeat Source Game server for the kids to play on. Steam Sockets is also offered as part of the Steamworks SDK for third-party game developers, with the vulnerabilities found on both Steam servers and on its clients installed on gamers' systems. The four flaws (CVE-2020-6016 through CVE-2020-6019) were uncovered in Valve's Game Networking Sockets ( GNS) or Steam Sockets library, an open-sourced networking library that provides a "basic transport layer for games," enabling a mix of UDP and TCP features with support for encryption, greater reliability, and peer-to-peer (P2P) communications.
