SOL15274: TCP reassembly vulnerability CVE-2014-3000
Security Advisory
Original Publication Date: 05/20/2014
Description
The TCP reassembly function in the inet module in FreeBSD 8.3 before p16, 8.4
before p9, 9.1 before p12, 9.2 before p5, and 10.0 before p2 allows remote
attackers to cause a denial of service (undefined memory access and system
crash) or possibly read system memory via multiple crafted packets, related to
moving a reassemble queue entry to the segment list when the queue is full.
(CVE-2014-3000)
Impact
An attacker who can send a series of specifically-crafted packets with a
connection could cause a denial-of-service (DoS) situation, and although
extremely difficult, may be able to obtain a portion of kernel memory.
Status
F5 Product Development has assigned ID LRS-24061 to this vulnerability, and
has evaluated the currently supported releases for potential vulnerability.
To determine if your release is known to be vulnerable, the components or

Recommended action
If the previous table lists a version in the Versions known to be not
vulnerable column, you can eliminate this vulnerability by upgrading to the
listed version. If the table does not list any version in the column, then no
upgrade candidate currently exists.
If your LineRate installation is behind a firewall, you may be able to
configure the firewall to protect the LineRate proxy from this particular
vulnerability. Consult your firewall documentation for TCP out-of-order
packet support or TCP reassembly features. If your firewall can
reassemble the packet stream before passing the traffic to your internal
network, this workaround will ensure the vulnerability in the LineRate proxy
cannot be triggered.
Impact of action: Performing the suggested workaround should not have a
negative impact on your system..
