CVE-2024-31175Network attack vector

Service interruption via unchecked parser return

Published Sep 18, 2024 · Updated Sep 18, 2024

NULL pointer dereference in Open Networking Foundation libfluid 0.1.0 allows remote attackers to interrupt an OpenFlow controller service. The fluid_msg::of13::TablePropertiesList::unpack routine fails to check a return value before dereferencing a null pointer while parsing OpenFlow 1.3 table-property data. A network path to a controller that passes attacker-supplied wire-format messages into this routine is required, and the resulting failure causes denial of service without reported data disclosure or modification.
