Infradead maintains OpenConnect, a VPN client widely deployed for enterprise remote-access scenarios, where its vulnerability footprint, though narrow in product scope, skews strongly toward critical-severity outcomes. The recurring weaknesses—classic buffer overflows, memory-boundary violations, input-validation flaws, and information-disclosure issues—reflect the memory-safety demands of a native network protocol implementation operating in a trust-sensitive context. Defenders should prioritize updates to this client and audit exposure in environments where it handles untrusted network input; live severity and exploitation figures are shown alongside this summary.
