CVE-2009-4501: Buffer Overflow
First published: Thu Dec 31 2009(Updated: )
The zbx_get_next_field function in libs/zbxcommon/str.c in Zabbix Server before 1.6.8 allows remote attackers to cause a denial of service (crash) via a request that lacks expected separators, which triggers a NULL pointer dereference, as demonstrated using the Command keyword.
