K46535047: F5 TCP IPv6 vulnerability CVE-2016-9252
Security Advisory
Original Publication Date: Mar 23, 2017
Updated Date: Mar 23, 2017
Security Advisory Description
The Traffic Management Microkernel (TMM) in F5 BIG-IP systems before 11.5.4
HF3, 11.6.x before 11.6.1 HF2, and 12.x.x before 12.1.2 do not properly
handle minimum path MTU options for IPv6, which allows remote attackers to
cause a denial of service (DoS) through unspecified vectors. (CVE-2016-9252)
Impact
When this vulnerability is exploited, the system may experience a
denial-of-service (DoS) attack, which can cause the TMM process to restart.
Security Advisory Status
F5 Product Development has assigned ID 597394 (BIG-IP) to this vulnerability.
