Description
A vulnerability was determined in NASA cFS up to 7.0.0. This impacts the function CFE_SB_TransmitMsg of the file cfe_sb_priv.c of the component CCSDS Header Size Handler. Executing a manipulation can lead to memory corruption. The project was informed of the problem early through an issue report but has not responded yet.
Analysis
Memory corruption in NASA cFS up to version 7.0.0 via manipulation of the CFE_SB_TransmitMsg function in the CCSDS Header Size Handler component allows local attackers with low privileges to corrupt memory, potentially leading to denial of service or information disclosure. No public exploit code or active exploitation has been confirmed; the vendor was notified early but has not yet released a patch as of analysis time.
