flb_msgpack_to_gelf in src/flb_pack_gelf.c once caused buffer overflow and was fixed in Commit 4e7894d

Recurring vulnerabilities

The same issues advent in:

• influxdb_format in plugins/out_influxdb/influxdb.c
• pack_format_line_value in plugins/out_loki/loki.c
• msgpack_to_sd in plugins/out_syslog/syslog.c
• msgpack_to_syslog in plugins/out_syslog/syslog.c

Would it make sense to fix them by adding a value length check in the same way as Commit 4e7894d did?
