Due to the way the current PK API works, it may have not been clear for the library clients, how big output buffers they should pass to the signing functions. Depending on the key type they depend on MPI or EC specific compile-time constants. Inside the library, there were places, where it was assumed that the MPI size will always be enough, even for ECDSA signatures. However, for very small sizes of the MBEDTLS_MPI_MAX_SIZE and sufficiently large key, the EC signature could exceed the MPI size and cause a stack overflow. This test establishes both conditions -- small MPI size and the use of a long ECDSA key -- and attempts to sign an arbitrary file. This can cause a stack overvlow if the signature buffers are not big enough, therefore the test is performed for an ASan build. |
