The csnmp_read_table function in snmp.c in the SNMP plugin in collectd before 5.6.3 is susceptible to a double free in a certain error case, which could lead to a crash (or potentially have other impact).
The product calls free() twice on the same memory address, potentially leading to modification of unexpected memory locations.
