CVE-2018-3991

Estado: ModificadaCrítica (9.8)—

An exploitable heap overflow vulnerability exists in the WkbProgramLow function of WibuKey Network server management, version 6.40.2402.500. A specially crafted TCP packet can cause a heap overflow, potentially leading to remote code execution. An attacker can send a malformed TCP packet to trigger this vulnerability.
