Fix get_len_step when buffer_size==0. The intent of this test is to ensure (via static or runtime buffer overflow analysis) that mbedtls_asn1_get_len does not attempt to access beyond the end of the buffer. When buffer_size is 0 (reached from get_len when parsing a 1-byte buffer), the buffer is buf[1..1] because allocating a 0-byte buffer might yield a null pointer rather than a valid pointer. In this case the end of the buffer is p==buf+1, not buf+buffer_size which is buf+0. The test passed because calling mbedtls_asn1_get_len(&p,end,...) with end < p happens to work, but this is not guaranteed. |
