CISA: Patch These ICS Flaws Across Multiple Vendors

The US authorities have released a new industrial control systems (ICS) alert urging impacted organizations to patch key middleware or risk denial of service and remote code execution attacks.

The Cybersecurity and Infrastructure Security Agency (CISA) pointed to a series of vulnerabilities impacting open-source and proprietary implementations of the Object Management Group (OMG) Data-Distribution Service (DDS).
