Patch time!ZoneAlarm Security Advisory
A security vulnerability exists in specific versions of ZoneAlarm®, ZoneAlarm Pro, ZoneAlarm Plus and the Zone Labs Integrity™ client. This vulnerability is caused by an unchecked buffer in Simple Mail Transfer Protocol (SMTP) processing which could lead to a buffer overflow. In order to exploit the vulnerability without user assistance, the target system must be operating as an SMTP server. Zone Labs does not recommend using our client security products to protect servers.
Upgrading an affected Zone Labs product will remove this vulnerability.
