CVE-2024-31164Network attack vector

Component crash via unchecked parser return

Published Sep 18, 2024 · Updated Sep 18, 2024

NULL pointer dereference in libfluid 0.1.0 allows remote attackers to crash an OpenFlow component with crafted network input. The libfluid_msg fluid_msg::ActionList::unpack13 parser fails to check a return value before dereferencing a null pointer while unpacking OpenFlow 1.3 actions. No authentication or user interaction is required, and the bounded consequence is interruption of the component using the library.
