AI-suggested

Until a fix is available, avoid using flatcc on 32-bit systems or apply any vendor-recommended mitigations once published.

Description

flatcc versions up to 0.6.4 have an integer overflow vulnerability in the check_header function of the FlatBuffers verifier. On 32-bit builds, this flaw allows crafted buffer offsets to bypass bounds checks, leading to out-of-bounds reads before the buffer and potential process crashes.
