Cups Overflow: When your printer spills more than Ink

Elastic analyzes a disclosure of multiple critical CUPS vulnerabilities (several CVEs) that allow unauthenticated remote code execution via IPP and mDNS by registering malicious printers; the report reviews PoC exploitation (cupshax), impact across many UNIX-like systems, mitigation steps (disable cups-browsed, block UDP 631, patch CUPS), and provides detection and hunting rules to identify foomatic-rip/cupsd malicious activity.
