What fixes it

No source in this snapshot names a fixed version.

Description

The Perl SNMP trap receiver script shipped with Zabbix does not properly neutralize the ZBXTRAP record delimiter in trap content. This means someone able to send SNMP traps can inject a record targeting another host, resulting in a loss of integrity.
