Threats affecting pkg:github/dvidelabs/flatcc

flatcc versions through 0.6.4 have an integer overflow vulnerability in the check_header function of the FlatBuffers verifier. The overflow guard code is ineffective, allowing crafted buffer offsets on 32-bit builds to bypass bounds checks. This can cause an out-of-bounds read before the buffer and lead to process crashes.

flatcc versions up to 0.6.4 have an out-of-bounds read vulnerability in the __flatcc_json_parser_number function. This flaw allows attackers to read beyond the input buffer when parsing JSON numbers that end with a decimal point. Supplying crafted JSON input ending immediately after a decimal point can cause the parser to access unmapped memory, leading to application crashes.

A vulnerability was determined in Dvidelabs flatcc up to 0.6.3. This impacts the function align_order_members of the file src/compiler/semantics.c of the component Duplicate Symbol Handler. This manipulation causes reachable assertion. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. Patch name: 8b19ba4e992ebcad7f5970704d1afc5507fa5205. To fix this issue, it is recommended to deploy a patch.
