Valve developers have recently patched a severe security flaw that affected all versions of the Steam gaming client released in the past ten years. From a report: According to Tom Court, a security researcher with Context Information Security, the one who discovered the flaw, the vulnerability would have allowed an attacker to execute malicious code on any of Steam’s 15 million gaming clients. In the jargon of security researchers, this is a remote code execution (RCE) flaw because exploitation was possible via network requests, without needing access to the victim’s computer. Court says an attacker was only required to send malformed UDP packets to a target’s Steam client, which would have triggered the bug and allowed him to run malicious code on the target’s PC.
