BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, Link Controller, and PEM 12.0.0 before HF1, when the TCP profile for a virtual server is configured with Congestion Metrics Cache enabled, allow remote attackers to cause a denial of service (Traffic Management Microkernel (TMM) restart) via crafted ICMP packets, related to Path MTU (PMTU) discovery. (CVE-2015-7759)
Impact
A remote attacker may be able to cause the Traffic Management Microkernel (TMM) to restart using maliciously constructed ICMP packets.
Virtual servers using a TCP profile configured with Congestion Metrics Cache enabled are affected by this vulnerability. Congestion Metrics Cache is enabled by default for TCP profiles.
