The process_trap function in trapper/trapper.c in Zabbix Server before 1.6.6 allows remote attackers to cause a denial of service (crash) via a crafted request with data that lacks an expected : (colon) separator, which triggers a NULL pointer dereference.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
