Impact
Unauthenticated network peers can crash or reset the target process by sending malformed hub traffic, causing a complete denial of service. The attacker only needs network access to the inter-processor hub port.
Root cause
The deserialization handler uses assertion macros (FW_ASSERT) for input validation and allows an integer underflow during command payload size calculation.
Affected systems
F´ (F Prime) prior to 4.2.0
CVSS v3.1 · CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
Fix & remediation
Upgrade to F´ version 4.2.0 or later; if unable to upgrade immediately, firewall or isolate the GenericHub communication channels from untrusted peers.
$ git checkout v4.2.0AI-suggested. Run it in staging first and check it against the vendor advisory. Why?
NVD description
F´ (F Prime) is a framework that enables development and deployment of spaceflight and other embedded software applications. Prior to 4.2.0, Svc::GenericHub fromBufferDriver_handler deserialization is vulnerable because the receive handler uses FW_ASSERT for externally influenced deserialization status and type validation and permits a command payload size subtraction to underflow. When an unauthenticated inter-processor hub peer sends a truncated buffer, an invalid HubType, or a header-only command-dispatch payload, malformed hub traffic aborts or resets the process, causing denial of service. This issue is fixed in version 4.2.0.
