Buffer overflow vulnerabilities exist in FRRouting through 8.1.0 due to wrong checks on the input packet length in isisd/isis_tlvs.c.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
The product receives input that is expected to specify a quantity (such as size or length), but it does not validate or incorrectly validates that the quantity has the required properties.
