OVERRUN error (CWE-119) in file libmariadb/ma_stmt_codec.c

Hi,

I'm working on fixing errors provided by covscan on project mariadb-connector-c (3.1.6) and I have problem with solving one of them.

IMHO it's quite an important one, so I want to ask you if you can help me fix it.

This is log from covscan:
Error: OVERRUN (CWE-119):
mariadb-connector-c-3.1.6-src/libmariadb/ma_stmt_codec.c:1171: overrun-buffer-val: Overrunning array "dtbuffer" of 60 bytes by passing it to a function which accesses it at byte offset 253.

1. 1169| break;
2. 1170| }
3. 1171|-> convert_froma_string(r_param, dtbuffer, length);
4. 1172| break;
5. 1173| }

I tried to look at it but unfortunately there is a lot of stuff to process, so I'm kindly asking for your assistance.

Thank you so much
Lukas
