Test ID:1.3.6.1.4.1.25623.1.0.56109
Category:FreeBSD Local Security Checks
Title:FreeBSD Security Advisory (FreeBSD-SA-06:04.ipfw.asc)
Summary:The remote host is missing an update to the system; as announced in the referenced advisory FreeBSD-SA-06:04.ipfw.asc
Description:Summary:
The remote host is missing an update to the system
as announced in the referenced advisory FreeBSD-SA-06:04.ipfw.asc

Vulnerability Insight:
ipfw(8) is a system facility which provides IP packet filtering,
accounting, and redirection. Among the many features, while discarding
packets it can perform actions defined by the user, such as sending
back TCP reset or ICMP unreachable packets. These operations can be
performed by using the reset, reject or uncreach actions.

The firewall maintains a pointer to layer 4 header information in the
event that it needs to send a TCP reset or ICMP error message to
discard packets. Due to incorrect handling of IP fragments, this
pointer fails to get initialized.

Solution:
Upgrade your system to the appropriate stable release
or security branch dated after the correction date.
