Hello,
Attached is a patch to fix a segfault that I was experiencing on x86_64
Linux host running net-snmp 5.3.0.
The issue is that incorrect types are passed to netsnmp_hex_to_binary
which are cast unsafely causing a buffer overflow. I think the patch is
trivially correct, but if you want more details, please let me know.
Cheers,
scott.
