Heap-based buffer overflow in Microsoft Azure Service Fabric for Linux allows remote authenticated users to execute arbitrary code. The authoritative records do not disclose the affected component, attacker-controlled input, or incorrect memory operation beyond the weakness class. Exploitation requires high privileges, high attack complexity, and network access, but no user interaction.
